What are the records of centipedes, frogs and snakes in ancient books?

The ancients knew that centipedes made snakes, which can be traced back to a long time ago. In ancient China, there was a big centipede that could snake. Lu Dian, an official in the Song Dynasty, once said in Ya Ya that centipedes can make snakes. It suddenly met a big snake, so it grabbed the snake's seven inches and sucked its blood dry.

In ancient times, people not only knew that centipedes ate snakes, but also knew that snakes ate frogs and frogs ate centipedes. Guan Yinzi Shan Zhi, a Taoist work in the Southern Song Dynasty, said: "Snakes eat snakes, snakes eat frogs, and frogs eat mantis maggots and eat each other."

There is a similar description in Lu Dian's Ya Ya: "The maggot hits the snake. As the old saying goes, toads eat networms, networms eat snakes, and snakes eat toads. " The frog is replaced by toad here, but it still conforms to the actual situation of nature.
