What do you mean, a man who eats four meals and walks around?

All the people who eat and go are monks and Taoists.

The explanation of eating square rice is that monks and Taoists make a living everywhere, which also means that ordinary people can live anywhere. From: Shen Congwen's "A friend wearing an otter fur hat": "Changde, He Fu, Zhou Xi, Taoyuan, and beautiful women who eat Sifang rice within nearly a hundred miles along the river are all familiar with him."

It is often used to mean that monks and Taoists beg for alms everywhere for a living, and that ordinary people can live anywhere.
