What is the saying that there is a little gathering at the bottom of the bowl of Kanggan folk kiln and a plum blossom arrangement around four o'clock?

At first glance, this stippling is not naturally formed in the process of burning paper, but belongs to manual stippling. Personally, I think it should belong to a certain group or family. Because porcelain was a rare product in ancient times, ordinary people rarely had bowls, so this kind of thing would happen whenever there were large-scale activities at home. In order to get their bowls back conveniently, most people will make a symbolic mark on the bowls, and so should the four-corner clubs in this bowl!
