特工355(Agent 355)

特工355(1780年后去世)是美国革命期间女性间谍的代名,是库尔珀组(Culper Ring)的一部分。 特工355是美国的第一批间谍之一,真实身份未知。355这个数字是库尔珀组中的加密系统用来表示“女士”的数字。

生平

在库尔珀组的公文中,唯一直接提及特工355的是亚伯拉罕·伍德赫尔乔治·华盛顿将军的信。伍德赫尔形容她是“对这封信有帮助的人”。

特工355的真实身份仍然未知,但有关她的一些事实似乎很清楚。作为间谍,她在美国独立战争期间与美国爱国者(或称美国辉格党,革命党)合作。她本会被伍德赫尔招募进间谍组。355这个代码表明她可能具有“某种程度的社会突出性”。她可能生活在纽约市,并且在某些时候与约翰·安德烈少校贝内迪克特·阿诺德有过接触。 一个可能是特工355的人是伍德赫尔的邻居安娜·斯特朗(Anna Strong)。另一个说法是,特工355可能是罗伯特汤森事实上的妻子。有传说表明汤森爱上了特工355。约翰·伯克和安德里亚·梅耶尔通过间接证据证明她可能与约翰·安德烈少校和本杰明·塔尔马奇关系密切,从而保护伍德赫尔不被指控为间谍,这为355参与间谍活动提出了不同的理由。特工355的其他可能候选人包括Sarah Horton Townsend和Elizabeth Burgin。

偶尔也有一些说法,说根本没有特工355,355仅仅代指一名知道有用信息的女人,并没有与特工组正式关联。代码355仅仅表示“一个女人”,而不是一个女性特工。

探员355被认为是揭露阿诺德和逮捕少校约翰·安德烈的主要角色,后者在纽约塔潘被绞死。她可能是一个著名的保皇派(或称托利党)家庭的成员,这个家庭背景使她很容易接近英国指挥官。

1780年,本尼迪克特·阿诺德(Benedict Arnold)前往保皇派那里,这时特工355被逮捕。她被囚禁在泽西号军舰上,这是一艘监狱船,在那里她可能生下了一个名叫小罗伯特·汤森的男孩。她后来死在监狱船上。然而,亚历山大·罗斯不同意这种说法,他说“女性没有被关在监狱船上”,“没有任何出生的记录”。这强化了355号特工可能是安娜·斯特朗的观点,因为她的丈夫塞拉·斯特朗被囚禁在泽西岛,她应该可以给丈夫带食物。她出现在船上使人们传言特工355被囚禁在那里。

在流行文化中

特工355已经成为通俗小说的一部分。她是《Y:世上最后一个男人》中一个主要角色。她也是现代间谍355的灵感来源,并收录在《刺客信条3》的游戏内历史事实数据库中,她的信息对于帮助主角发现要捕获的英国阴谋至关重要。

在电视剧《逆转奇兵》(Turn: Washington’s Spies)中,特工355是一位名叫阿比盖尔(Abigail)的前奴隶,安娜·斯特朗曾是她的主人。英国军队在安娜·斯特朗入狱后没收了他的财产。虽然名义上阿比盖尔是自由的,但她被迫为约翰·安德烈工作。阿比盖尔把她在安德烈家中无意中听到消息藏在给儿子的礼物中,这个儿子被迫留下交给安娜照顾。剧中,特工355由伊达拉·维克托扮演。

Is the Perfect the Enemy of the Good?

Voltaire once said, “perfect is the enemy of the good.” And as a perfectionist in recovery, I can say without hesitation, the boy was he right!

Having high standards motivates us to work hard and to excel in life.

However, the desire to be perfect only handicaps us. It stops us from doing what we’d really like to do. And if it doesn’t, it deprives us of the pleasure of enjoying what we pursue.

Here’s what happens when we reach for perfection:

We become Haunted by Failure

Under the false illusion that our path in life should be a straight line, we become terrified of curves and detours. Nothing sounds more catastrophic than the idea of making a mistake. So we become scared to death of taking risks. Of going beyond the unknown to try something new.

We don’t see failure as an opportunity to learn and to grow. But only as the most intimidating threat to be feared. So we do everything in our power to avoid it at all costs. Even if it means we stop living.

We Fail to Enjoy Success

If we see failure as our enemy then success would be our foremost ally, right? Well no. Even if we succeed, our expectations are such that any success is perceived as trivial. When we accomplish a goal we underestimate it. And fail to savor it.

There’s always something that could have been done better. A mistake that could have been avoided. A detail that shouldn’t have been missed. In the end, there’s always something that we failed to do, even if we succeeded. Because we failed to be perfect.

怪屋女孩:灵魂博物馆

刚刚读完了 Library of Souls - The Third Novel of Miss Peregrine’s Peculiar Children

我读这本书其实是为了学英语,但作为一本冒险小说,设定还是很有新意的,尤其是那些照片,还有男主的女朋友!

不过,这种故事是典型的英雄之旅(Hero’s journey)的模版。读到最后,回忆主角经历的种种,恍若隔世,还是蛮温馨的。


接下来是我的笔记,见笑了。

She wished me luck and kissed me on the lips. Then I looked at Sharon, who tilted his head at me as if to say, I hope you’re not expecting a kiss from me, too, and I just laughed and walked toward the fighters.

这个梗在漫威电影里面也有用到

Just because I’m a capitalist doesn’t mean I’m a black-hearted bastard.

我是一个资本家,但这并不意味着我是一个黑心的混蛋

“Gold coins!” said Emma, fairly spitting with disgust. “What about the well-being of your fellow peculiars? What about loyalty?”
Sharon chuckled. “If I cared about things like that, I’d have been dead long ago.”

Sharon说的很有道理,居然无法反驳

He was a hoarder, like his brother, of strange and ghastly things—only where Bentham was organized to a tee, Caul badly needed a maid.

badly needed,哈哈

“In the tales that are told about us after our victory, I should like to be known as Addison the Intrepid.”
“And so you shall,” said Emma.
“Make that Extremely Intrepid,” Addison said. “And handsome.”
“Done,” I said.

这两个应该算是英式幽默吧,Addison Intrepid and Handsome!

Billionaire

The topic is billionaire, namely, If you had a billion dollars, what would you do. How about browsers billionaires firstly? No, it isn’t interesting. What can we do with those non-existent one billion dollars? Hey, I am a man, the cosmetics, the luxuries, will not be on the top of the list. The simplest thing is buying an island, for fun? I can’t find the reason. Seriously, The spacecraft can be the first. There are space stations built by NASA(acronymized by National Aeronautics and Space Administration) and CNSA(acronymized by China National Space Administration). But I prefer crewed spacecraft because I could be a crew. The second can be supporting research institute. How about research on immortality? It sounds like perpetual motion, does it? Namely, it’s medical research, that we can prolong the lifespan until eternity. When a  scientist states that something is impossible, he is very probably wrong. And the cosmology research is what I want to sponsor if the money is enough. Earth is the cradle of humanity, but one cannot live in a cradle forever. But, one billion dollars isn’t enough, neither for research or spacecraft. The budget is certainly limited, right? Here is some billionaire we mentioned: Rockefeller, an American oil industry business magnate, had 400 billion dollars. But Rockefeller has died, so let’s move on. Zuckerberg, Facebook co-founder, also a philanthropist, has 56 billion dollars. Larry Ellison, Oracle co-founder, has 59 billion dollars. Larry Page, Google co-founder, has 53 billion dollars. Bill Gates, Microsoft co-founder, has 95 billion dollars. Jeff Bezos, Amazon co-founder, has 137 billion dollars. OK, as a former developer, I’m over-focused on IT sphere. Liliane Bettencourt, the founder of L’Oréal that I never heard it, had 44 billion dollars. Kjeld Kirk Kristiansen, the former CEO of The LEGO Group, has 5 billion dollars. Sheldon Adelson, the founder of Las Vegas Sands, has 43 billion dollars. And, maybe the most famous one, Donald Trump has 3 billion dollars. How about Chinese? Jack Ma, the founder of Alibaba, has 34.7 billion dollars. Pony Ma, the founder of Tencent, has 42.7 billion dollars. Robin Li, the founder of Baidu, has 18.8 billion dollars. Wang Jianlin that is famous for her son has 28.1 billion dollars. And, Richard Liu, the founder of JD, that is infamous for the sexual assault, has 12.7 billion dollars.

The woman on the bus was molested

On 25th, Sep, domestic violence happened at a bus at Beiliu City, Guangxi Provence. According to the video, a woman moved to bus’s roar exit gate, trying to get off at the next station. The man pulled the woman off the rear of the bus while the woman tried holding on the handles. The man threw the girl to the last row of seat and sat beside her. The woman was screaming throughout the video. At first, the video is thought to have happened at Zhongshan City, Guangdong Provence. After investing, police at Zhongshang declared that it didn’t happen in Zhongshan. Later, a reporter contacted the police in Beiliu City, Guangxi Provence, which confirmed the violence happen at Beiliu City, Guangxi Provence. Sadly, the police’s response in the video shows the lack of legal knowledge:

“The man and the woman are factual marriage, which means they haven’t registered, hadn’t a marriage certificate. They have one child. The woman is too young to register for marriage. And the police has told the man not to use violence.”

According to Chinese laws, the statement from police doesn’t make sense. Factual marriage was deprecated since 1994, and it should be considered illegal cohabitation. The police should know it well. By all means, neither the marriage or the child doesn’t make the domestic violence legal. So, Why didn’t the police protect the woman? We should notice that no one stood up to protect the woman at the bus. But the most important things is the police just tried to muddle through, not protect the woman.

A freshman was expelled, because of killing a stray cat

In 10th, Sep, a stray cat was killed, by bows and arrows. A member from the animal protection society of HBUE(Hubei University of Economics) said that the cat was found in the trash, then sent to the hospital for surgery. Unfortunately, the cat was dead. He said, “When he is killing the cat, His friend is recording video” In 18th, Sep, HBUE announces that the cat-killer is a freshman from further education college, enrolled in 2018. And, the killing didn’t happen on campus. The police were investing. In 20th, Sep, the college announces that the freshman was expelled. That’s what happened.

Is there any law he violated?

Strictly, It’s Cruelty to animals(according to P.L. 89-544, which is American law). But in China, there isn’t a specific law to protect pets. Sadly, the freshman’s behave isn’t illegal.

So, how about regulations?

According to the college’s announcement, [caption id=”attachment_924” align=”alignnone” width=”750”] Announcement from HBUE, source: https://weibo.com/2174871542/GAfikEJlx\[/caption\] the college just announces the punishment but doesn’t give the specific regulations. It’s really unprofessional. It seems like we punish him, just because he violated the regulation which doesn’t exist. When some bad thing happened, we should think about it. Why there isn’t a low for an animal’s welfare? We shouldn’t be happy just for punishment without clear regulation. At the same time,

Today he kills the cat. Tomorrow, He will kill people.

is widely spread in Weibo bizarrely. They asks for punishment with one voice, but not for a fair law.

Let’s narrow it to laws and regulations:

  • The college should explain the regulation that the freshman violated.
  • The animal protection society should peal for making animal protection law, not just asking for punishment for a specific man.
  • The stray animal should be protected, restrained properly.
  • The eco-catastrophe caused by the stray animal should be seriously discussed.

The story about Chang(伥)

First and fomoest, Chang(伥) is a kind of Chinese ghost. Some ancient Chinese books describe Chang.

Guangyiji

In Tang dynasty, Dai Fu, written a book Guangyiji, to record mysterious, supernatural things. At chapter Xuanzhouer, he writen,

At the end of TIANBAO(C.E. 742-756) in Tang dynasty. There is a child living near to the mountain, at Xuanzhou. Every night, he always seeing a ghost leading a tiger to cheat himself. This happened more than ten times. The child told parents, “I will die because the ghost was leading a tiger. People are saying,’If someone is eaten by a tiger, then he will become Chang’. I will become Chang, if I died. If that happened, I will lead tiger to village. You can set a trap in the road it must take, and you can catch a tiger”. Several days after, the child died by the tiger. long time after, his father have a dream that the child said, “I have been Chang already. I will lead tiger to village. You can set a trap in the west of the village.” The father set the trap. when the trap was set, a tiger was caught.

Beimengsuoyan

In book Beimengsuoyan, which was written by Sunguangxian in Ming dynasty, recorded:

One died by tiger, or drown in water, will become Chang. They must seek someone to replace themselves.

This is a definition of Chang. But later, Chang’s meaning narrowed to a ghost was died by tiger.

The book named Zhengzitong, Tingyujitan, which was written in later years of Ming dynasty, give more detail about Chang:

"For Freedom!" and following performance was canceled

Here are the original report of Süddeutsche Zeitung:

He has the impression, wrote one on the Internet after the performance of Henrik Ibsen’s “People’s Enemy” by the Schaubühne Berlin in Beijing, as if “the chickens wanted to tell the ducks something”. It can happen that chickens and ducks talk to each other. For example Norwegians with Germans, Germans with Chinese and the creatures of existing capitalism with those of newly inventing socialism. That a text from the 19th century is addressed to an audience from the 21st, and the audience then turns to the actors. And that it becomes turbulent. It may be that those in charge at Beijing end of last week were fully confident in the old Chinese wisdom that chickens and ducks do not understand each other anyway. But it can also be that the poultry suddenly discovers that it speaks a common language. And that this discovery makes those responsible so upset that they first want to pull the plug. The Schaubühne is not a freshman in China. The ensemble has performed here more than 40 times over the past four years. The website of the National Theater in Beijing praises her as a “dream team” of the German theater world, which now enjoys a “legendary” reputation in China. The “People’s Enemy” staging of the Schaubühnen director Thomas Ostermeier states that it is of “dazzling brilliance”. But whether one of the Beijing censors watched the play before the premiere last Thursday? Rather not. A classic, they will have thought, 130 years old, what should go wrong? Otherwise it would hardly have come to the excitement after the performance, to a crisis meeting until dawn, to the demands on the German ensemble, they should immediately remove the offensive place from the play, for the immediate stop of ticket sales. The brief News of the Beijing News said: “The play ‘People’s Enemy’ is being ‘adapted’ and the sales channels will be closed.”

Shortly before the end of the play the bath doctor Dr. Ing. Stockmann a speech to the citizens of his community. He wants to warn them about poisoned water and the corruption of the dignitaries of their place. Ostermeier used excerpts from the anti-capitalist pamphlet “The Coming Uprising”, which caused a sensation in France after the 2009 financial crisis. Above all, he lets the scene flow into a dialogue with the audience. Tobias Veit, director of the Schaubühne, says the ensemble did not know what to expect in Beijing. “And then we were flattened,” he says. For 15 minutes, the audience called up the reasons for their sympathy with the main character to the stage. “Because we are for the freedom of speech”. “Because China’s media does not speak the truth.” “Because our government acts just as irresponsibly here.” One could read the scene for a short time in the social media, something in the Wechat account of the viewer “Jingerna erjingxiaoshi”: “I was sweating inside,” he writes. “I thought: pronouncing such things in the National Theater - are not they afraid of a ban?” For a short time, the ban actually stood in the room: the functionaries of the theater made it clear to Veit that further performances take place only if the actors renounce the dialogue with the audience. This could raise “misunderstandings”. The ensemble then advised, says Veit - and decided against a rejection: “We would have left scorched earth, and the scandal would have had a forum in Germany alone,” says the director. The actors decided to shorten the dialogue, but to mark the censored passage as such: “The audience should know that something has happened here, that something is missing”.

The spectators sympathize with the upright, who puts on the power

It has celebrated the “enemy of the people” as a criticism of capitalism and democracy. And now Ibsen’s play in China is perceived as a mirror of the circumstances. Amazing? Not really. Fraud, hypocrisy, cover-ups by the authorities and the media, a swamp of corruption, a “bottomless poisoned society”, the lone fighter for the truth, who is declared a “madman” are all too familiar to humans. Friday evening. It’s the first performance after the near miss. Stockmann gives his speech. Then the question of the publisher Aslaksen: Who agrees with the speaker, the radical, the madman? Almost everyone in the hall in Beijing raise their hands. To assume that they do not care about the speech just given. They sympathize with the upright, who has taken on the power. Some yell. Demand: Do you even understand what he said? An older viewer can no longer hold to himself: “For the rights of the individual!” calls he. “For the freedom!” Occasional “Bravo!” Calls sound. The actors are standing on the stage, silently. “Dear spectators,” says the physician Stockmann (Christoph Gawenda), finally, “at this point a dialogue should actually have taken place with you. - he tears open the publisher (David Ruland) - “the Mr. publisher has no voice”. “Incredible,” says one of the viewers in the foyer of the National Theater, “100 years old - and I recognize the China of today”. His companion pulls out her cell phone. “Oh,” she says. “I better not put that on Wechat. Too tricky.”

Currently, the planned performance in Nanjing City, Jiangsu province, was canceled by “stage technical reason”: [caption id=”attachment_915” align=”alignnone” width=”1634”] the planned performance in Nanjing City, Jiangsu province, was canceled[/caption]
