I want to ask, "Shuang Yan has gone back to the south, and is here to find Wang Xie Gu. Don't doubt Huatang's spring paintings. The liver sometimes has points, so why bother? " How to explain it?

Because there was a poem before, in the old society, Wang Xietang flew into the homes of ordinary people. This means that in the Jin Dynasty, Yan Zi was king in front of Xie An's two houses, but now he flies into the homes of ordinary people. Sigh the decline of the prosperous times. Here, "Shuang Yan went back to the south to find the king". It means two swallows fly to the south to find a rich family. Looks like a good sign.

The meaning of "Don't doubt Huatang's spring paintings, sometimes there are points in the liver, so why bother" is understandable. It should be that you don't have to worry about spring paintings (which should be fortune-telling), and your life will have everything, so you don't have to be busy solving it.
