Stuff you should know about China - Preface Stuff you should know about China, abbreviated as SYSKAC, will be the program for my writing improvement. The reason I undertake this is obvious: it would benefit both myself and the folks who kindly help me revise this writing. On one hand, I could develop my writing skills with your help; on the other hand, the readers and correction-providers can develop a better understanding of China. The program will have a wide range of topics, including politics, history, culture, economy, as well as entertainment. Limited by the knowledge, I can not guarantee that all my viewpoints are correct, but I'll try to showcase them in a perspective regarding of my own experience as neutral as possible. The ugly will not be masked intentionally, while the petty will not be promoted deliberately. As has been staying in both China and western countries for many years, I experienced the occasions that certain outside news is blocked by the state-run firewall and public opinions are extravagantly censored, I also encountered the scenarios that true stories of China are exaggerated or even distorted by the biased western media. It has to be confessed that the display of the "absolute truth” is impossible due to my knowledge limitation, and the understanding of it is also contentious subsequent to different ideologies and experience of individuals. Whereas, I hope that the clips I show you subsequently can help you approach closer to the truths and establish a more accurate understanding of China. May the world get better by communications.
