It is sometimes difficult to define what is right and what is wrong. Because there are corresponding causal conditions behind every right or every wrong. That is, something seems right at the moment. After a period of time, as the situation changes, what is right has become what is wrong. Equally, you cannot use a current conclusion to refute a viewpoint from the past. Xue Mo
