mosquito net
Mosquito net Originated in the Spring and Autumn Period in China, it is a tent to avoid mosquito bites, and it is an essential bedding in southern summer. Mosquito nets are usually hung on the bedstead to enclose the bed to isolate mosquitoes. Mosquito nets are mostly mesh, which can avoid mosquitoes and wind, and can also absorb dust in the air. It has the advantages of environmental protection, air permeability, convenience, durability and repeated recycling.
Historical background
During the summer and autumn, mosquitoes raged, and the ancients complained about their troubles very early. More than two thousand years ago, Zhuangzi Tian Yun said: "Mosquitoes licking the skin will make the past (dusk) sleepless." Fu Xuan, a native, also wrote a special article "Mosquito Fu", in which he said that mosquitoes "eat their skins to satisfy their hunger, hinder Nanmu's farming, and waste women workers", which is really harmful.
In ancient China, curtains were the main anti-mosquito tools. Its earliest name was "Yang". During the Spring and Autumn Period, Qi Huangong (reigned from 685 BC to 643 BC) made it impossible for hungry mosquito camps to enter. This record can be found in the Spring and Autumn Annals, Guoyu and other pre-Qin historical materials, and only exists in Xiao Yi's Jin Lou Yan Zili.
Well, maybe there's another way to write it. There are two words "Su Su" and "ghost" in The Book of Songs Zhao Nanxiao Xing. Mao Zhuan is interpreted as a quilt, and Jian Zheng is interpreted as a bedsheet. Zheng Xuan may be right. The words "Yi" and "Ai" are homonyms. They are homologous, and both refer to bed sheets. The word "Zhang" commonly used in mosquito nets today, because it was used with "Zhang", did not become attached to the bed curtain until the Qin and Han Dynasties.
The original "account" only refers to the curtain, camp, military account and so on. So Er Ya in the early Han Dynasty began to say, "The description of the name." Liu Xi explained the names of people in the Eastern Han Dynasty and said, "Zhang Ye, Zhang Ye, applies to beds." Since then, there have been various names such as "mosquito", "mosquito", "mosquito" and "mosquito net".
