why I'm talking about immigration Last year, in a concert I encountered my boss and his secretary, a young lady. Obviously, they were dating. May you not know that of my boss, his family, including his wife and their only son, has settled in Canada for years, and it’s said that he lives alone in Shenzhen. I can see how tough the life is for him, he is always busy with work but careless of himself --- someone said sometimes he didn’t have lunch or just had an apple. At the moment, It made me curious to dig deeper into the issue of the immigration which would result in the problems of the split of family.
