When we return and are reincarnated as women , then we are different . no one is always perfect or always a woman . there is no need for jealousy here but human beings did not know that and they still do not know that 我们就是生而如此，当我们轮回为女人身时，我们就不再像男人那样，没有任何人会一直是完美的，或一直都生作女人，所以其实没有必要嫉妒什么，但是人类以前不了解，到现在也还是不明白。
