Deutsch und ich Ich möchte ein Erfahrung über Deutsch von mir für euch erzählen. Als ich 14 Jahre alt, machte ich einen deutschen Stiftkumpel namens Inken. Wir schrieben etwa zweimal pro Woche E-Mails in Englischer Sprache. Sie ist meine erste ausländische Freundin. Sie war 16. Sie hatte einen Freund. (Auch Ich möchte einen Freund. Aber das warst selten in China. Leider.) In der Schule lernte sie Religion. Sie buchstabierte “history” als “historie”. Sie sagte, Deutsche tragen nicht immer Lederhosen. Das waren sehr interessant. Ich habe ihr auf Chinesisch gesagt: Deutsch bedeutet Moral und Willenskraft. Sie war überrascht. Und Sie hat mir ein Deutsch beigebracht: “Ich liebe dich”. Ich liebe dich! Das ist schön! Wir haben jetzt den Kontakt verloren. Aber diese Erfahrung ist immer in meinem Herzen.

A war in cyber Fans who support Xiao Zhan have raised great fury in Chinese online social media. Weibo has become a churning ocean debating about whether we can tip-off or report about what we dislike in social media. It seems familiar for a sensible Chinese child to report their teacher that a classmate was reading comic books in class. Let's put the discussion on whether this kind of sensibility is adorable aside today. Let's see this reporting habit that the culture and society nurtured as a pusher today. The fans neglected the seriousness of reporting government. We come to a platform to communicate, to enjoy the culture and cyber life. But it is a problem whether we have the power to stop others from enjoying what they enjoy, but we dislike it. This boundary is hard because we cannot measure one's likes to another's dislikes. But generally, I agree that within the culture and art world, diversity is better than purity. I also can't entirely agree with the shut-down behavior of our government. They have been too reckless to shut down all the platforms. It is a rogue's behavior! I wish I could live in a world where all can enjoy what they like, be what they want to be, and the society is healthy and robust to face setbacks directly and is powerful to improve. Why in English it is back to the future, rather than forth to the future?

Why it is "back" to the future? Is future behind us? Why in English it is "back" to the future, rather than something like, "forth" to the future? Do English speakers think they face to the history and the future is behind them?

egoism & egotism Hi, I want to know the difference between "egoism" and "egotism". Do they all mean something related to selfishness?

A reflection on causality The question that what defines caulsality has long been discussed since the ancient times. Aristotle has raised four kinds of causes, namely, material cause, formal cause, efficient cause and the purpose. In modern science, disciplines follow different academic traditions. Some focus on chronological sequence of events, while others mostly rely on statistical models. A graduate student may wonder where to start to deal with it. After all, they have to go through a long period to learn to analyze causes and build their theoretical basement. That is not easy, because the basement should be both rational and also fit for the them to do following researches.
