Around a decade ago, having been restricted by many government policies in China, I was chary of really putting all my energy and passion into pursuing a long-term thinking and career. Essentially I didn't trust there's a real guarantee or something that the gains of my efforts wouldn't be lost because the government could and would change its pervasive policies freely at any time which can be either expected or not expected by me. So I came to Canada when the opportunity presented itself.
Nowadays, it seems that many people feel the same way as I did many years ago, despite the fact that many reported individuals among them are rich but I was poor. See this NYT news piece: Harassment and Evictions Bedevil Even China’s Well-Off.
I can say that I always want to expend the time of my life charily and I cherish that time.
