Old Sha wrote about living in Japan for eight years and preparing to leave. It was supposed to be like a peaceful breakup after a failed relationship, simply stating a reason. Unexpectedly, so many lovesick men and women jumped out of the timeline, insisting he was wrong, that he should have followed the rules, shouldn't have disturbed others' peace, shouldn't have left, and that he should have just gotten out of there. Seriously, how much do you know about his life? These idiots probably can't even see how comfortable he is in Japan. Just look at his Japanese wife—she speaks fluent Chinese and is incredibly smart and lovely. You say he can't integrate? Go and try integrating yourself! Those who always like to lecture others should use that time to live their own lives well. The world is complex; every place has its advantages and disadvantages. If you have the ability to choose, the motivation to move, there's no right or wrong. You can admire, but there's no need to be jealous. Jumping up and swearing is just inelegant.
