The ancients thought that Lingnan area was a "land of narrow escape" because there were many mosquitoes there?

In fact, the ancients thought that Lingnan was a place where people survived, mainly because technology was backward at that time and many diseases could not be solved correctly, which led you to become a place where people survived. In fact, the mosquito danger in Lingnan is on the one hand, mainly because you can go to the tropics, and the weather is hot and humid, which is easy to breed bacteria. What you and I are saying now is that Lingnan should belong to the subtropical zone. Before the opening up, there was a large jungle in Lingnan, which was very dangerous.

In ancient times, it was said that there was a miasma in Lingnan that could make people sick. Actually, let me explain miasma, which is actually a common disease in Lingnan. It is recorded in Lingnan Series. Miasma is a kind of typhoid fever. Due to the backwardness of ancient science and technology, it is impossible to sterilize on a large scale, which leads to the breeding of various infectious diseases. In addition, the ancients had no awareness of infectious diseases and did not know how to isolate the source of infection and block the route of infection. In this way, the news spread. Miasma has also spread widely, causing numerous deaths and injuries.

Han Yu once wrote these words, knowing that you will feel something when you come from afar, so that you can put my bones in the river. It can be seen that ancient people were afraid of Lingnan. The worst thing in southern Fujian is not mosquitoes, but malaria. Due to the unique climate and backward science and technology, malaria is rampant in Lingnan area. In ancient times, there was basically no solution to this infectious disease. Generally, if you get it, you will die, and your death is extremely miserable and painful. So this has aggravated people's fear of Lingnan.

Lingnan is also known as the barren land. This place was originally inhabited by barbarians, plus all kinds of poisonous insects. In ancient stories, people believe that there are witches in Lingnan area who can cast spells to poison large people. In fact, it is a description of malaria in ancient Lingnan, which caused numerous deaths and injuries. Therefore, Lingnan has been called the land of narrow escape since ancient times.
