"Peng Zu is a no-no, B does not plant thousands of plants, and it is not good for the groom to marry." What does this mean?

This is Peng Zu's "bogey" in two sentences, meaning:

-If you don't plant thousands of trees, you won't grow long: don't plant trees in B, because the trees planted at this time are not conducive to the growth of trees.

-Don't marry a bad groom: Don't hold a wedding in Shanghai. It's not good for the groom to hold a wedding at this time.

This is a folk taboo in ancient China, which is intended to remind people to pay attention to certain things at certain times to avoid bad consequences. However, these taboos do not necessarily apply to everyone in modern society, but are widely spread and passed down as a cultural tradition.
