White Deer Plain TV Series Although I am a Chinese by ethnicity but growing up in my country means you don't have a chance to learn Chinese literature. Recently, I have been watching a TV that dramatize by a Chinese literature novel called White Deer Plain（白鹿原 bái lù yuán). White Deer Plain Talking about how Confusion traditional culture has been Impacted by era evolution and political movements. There is two established family in the story, One family follow the Confucian political ethics and they are conservative and the second family is misbehavior yet open minded. The second generation of these two family goes to the different direction. It reminds me of a quote that I've been read from a global history book saying we must completely destruct the traditional in order to accept the new. History is always surprisingly similar. If you are interested in how China transform into a fast developing country, why most of the Chinese are an atheist, you have to watch this TV.

Sport Injury Tennis is one of my favorite sports.I go to play tennis after work every day.But these two days, I didn't go to play tennis because my knee was hurt. My knee problem was an old injury happened three years ago when I do HIIT with my personal trainer in the gym.I feel really pain these two days even I walk normally. I feel a little empty when life after work without tennis. Talking about sports injuries it reminds me of something. Some sports “fans” pitch up sports player when they couldn't get a champion in the tournament or competition because of injuries. People just cannot feel the same way of how hurt it was. When you have a sports injury, you will feel hopeless and helpless cause your body just couldn't listen to you. I've met a 3D printing startup last week.
