As the weather gets hotter, there are more mosquitoes. People probably have the same experience. When they are going to sleep at night, they will be woken up by the buzzing mosquitoes. They especially want to turn on the lights to see where the mosquitoes are. Once the lights are turned on, the mosquitoes disappear, and when the lights are turned off, the mosquitoes appear again. Summer is probably a time to fight against mosquitoes. There are mosquito swatters in modern times, but there was no such high-tech gadget in ancient times. How did the ancient people repel mosquitoes?

　　The first is the comfort therapy that scholars like. This consolation therapy is very simple, it is to write articles to vent hatred and dissatisfaction with mosquitoes. Such representative works include Zhuangzi's tianyunpian, Ouyang Xiu's disgusting mosquitoes, and Li Yu's leisure love. Among them, Ouyang Xiu's Zui is remarkable. First of all, he describes the small size of mosquitoes, then describes the noise of mosquitoes, and then talks about mosquitoes biting people and packing. After Zui, Zui concludes that there are too many mosquitoes.

　　It seems that both ancient and modern people have a great hatred of mosquitoes. This consolation and catharsis therapy, of course, is useless. The method commonly used by ancient people is smoking. Ancient people found that mosquitoes were afraid of smoking, especially the smoke from burning wormwood and chrysanthemum chrysanthemum, which could kill mosquitoes. In the summer, people will wormwood and chrysanthemum into a rope shape, made of mosquito repellent tools fire rope. The method of using the fire rope is very simple, that is, ignition. Although the smell is not very good, but the goal has been achieved.

　　This fire rope can't be carried anywhere. Moreover, after burning, it smells very bad. Walking past other people, it has a bad smell, which affects the personal image. Some ancient talents thought, this is not to delay my younger sister, the rope must be improved. So the sachet was born. Sachets are filled with some good compatibility of mosquito repellent medicine, such as moxa leaf, Huoxiang, mint, borneol, honeysuckle and so on. These things are the mosquito Zui hate, people wear this kind of sachet to go to the street, it's just like a human toilet water. This is why there were no mosquitoes in a street of traditional Chinese medicine in Bianjing, the capital of the Northern Song Dynasty, for a whole summer.

　　Of course, some people at the bottom of the society take biological therapy to prevent mosquitoes. This biological therapy is very simple, that is, a large water tank is placed at the door of the sleeping room, and several frogs are raised in the big water tank, and the mosquitoes are eaten by the frogs before they fly into the room.

　　Even so, sometimes there will be missing nets of mosquitoes, mosquito nets will shine on the stage. Mosquito net Zui appeared in the spring and Autumn period. Qi Huan used transparent gauze to surround his bed, and thus the bed net was born. In the Song Dynasty, mosquito nets were accepted by the whole people. Even if they were poor, they had to buy them. To this day, mosquito nets are also hot sellers.
