Like father like son 有其父必有其子

Once a boy's grandfather beat his grandson for playing with fire in the courtyard.

The boy's father saw this and he got worried about his son. So he took a stick and began beating himself. The grandfather was surprised and asked:

"Why are you beating yourself?"

"You are beating my son and I'm beating your son." The boy's father answered.

一个小孩因为玩火被爷爷打了一顿。

孩子的父亲看到后很心疼自己的儿子。因此，他拿起一根棍子开始打自己。孩子的爷爷见到后很不理解，便问道：

“你为什么打你自己呢？”

孩子的父亲说：“因为你打了我儿子，所以我也要打你儿子。”
