How to avoid rats when storing grain in ancient China?

Although the methods of acupoint fumigation and water irrigation are good, they can only drive away rats temporarily. Later, people began to use poison and equipment to kill rats. For example, in the Book of Power in the Tang Dynasty, it was recorded that "lifting a stone can harm mice ... mice are drunk, but they know how to drink mud juice and calm them down in a moment". This is a method of killing rats with minerals that people in the Tang Dynasty explored through experiments.

In fact, the ancients have long noticed how to poison mice with drugs. "Xishan Jing Shan Hai Jing" records: "There is a white stone named Ju, which can poison rats. There is grass, which looks like medicine, leaves like sunflower and red back, which is called "no strip, which can poison rats" People not only found that alunite can poison mice, but also found that some plants can be used as poison to kill mice.

"Jiao's Yilin" has: "Moxibustion fish fights, waiting for night rats, can't bear to smell incense, and tussah can't go", which is a record of the use of mousetraps in ancient times.

In addition, people have come up with some strange tricks to drive away rats. Qi's "Yao Min Shu" records: "Huainan Wan Bi Shu said: the fox looks at the raccoon, and the mouse goes to its hole."
