This is another way to congratulate someone. You are genuinely happy that another person has achieved success, gotten married, had a baby, plus many more situations that would take an entire book to through. It is healthy to be happy for other people. jealous people often want others to unhappy.

真为你高兴

　　这是祝贺别人的另一种方式。别人取得成功、娶妻生子等等，你真诚地为他高兴，这种心理结合别的情况可以写一大本书。为别人而高兴很正常，好忌妒的人常常是希望别人不高兴。
