The first time I saw my mother crying, I was so sad. Tell me about it.

I used to always make my mother cry. Every time my mother cries, I feel very sad and regret facing her. Now I am a mother, so I can understand the mother's hardship. Anyway, as children, we all have the responsibility to make our parents happy. We can't let their sweat flow in vain. Filial piety to our mother. After all, no one knows when she may leave and never see that face again. It's no use crying.
