What is the "salt rat" that old people often say?

The salt rat is actually a bat, which means that the bat is a name and the salt rat is a nickname. Because of a legend, the old man called it a salt rat. It is said that the salt mouse was originally just a mouse running on the ground. Later, after stealing a lot of salt, it grew wings and became a flying mouse, so it was called a salt mouse. There is also a name called. Rats under the eaves? Two kinds of salt are homonyms, but the origins of these two names are different. It is called the house-eaves rat because bats live under the eaves in front of and behind the house for a long time.

In fact, bats are mammals. They like to live in caves in mountains and cracks in tile houses. Generally, it is difficult to see bats during the day, but at night or when it is getting dark, they will come out for food and activities in groups. But the species of bats are not very single. There are big bats and small bats. Generally, bats living under the eaves are relatively small. Their wings are thin and their bodies are petite. Their front legs are long, their ears are big, and their hair is usually brown, so they look a little creepy as a whole, so many people are afraid of bats.

Bats living in caves are usually very big, and most of their body hair is black, which looks scary. But no matter how ugly bats are, don't be afraid.

In addition, bats have a great advantage, because bat excrement has medicinal value. Is bat shit also called in Chinese medicine? Night sand? As the name suggests, it is used to treat eye diseases, but now the number of bats is scarce, and rural houses are no longer mud brick houses, so the number is gradually decreasing.
