Introduction to masks
A mask is a sanitary product that is generally worn on the mouth and nose to filter the air entering the mouth and nose to block harmful gases, odors, and droplets. A device that goes in and out of the wearer's mouth and nose, made of gauze or paper.
Masks have a certain filtering effect on the air entering the lungs. When respiratory infectious diseases are prevalent and when working in a polluted environment such as dust, wearing a mask has a very good effect.
Masks can be divided into air filtering masks and air supply masks.
On January 14, 2021, the State Council Information Office held a press conference to introduce that China exported 224.2 billion masks in 2020. In February and November, four departments including the State Administration for Market Regulation jointly deployed and redeployed and strengthened the in-depth promotion of mask quality supervision.
Jin Yi "Follow the Old Horse": "At this time, he told me to pull the mask up and cover my nose to prevent flying flowers from getting into my nostrils."
The World China was the first country to use masks. In ancient times, people in the court began to cover their mouths and noses with silk scarves in order to prevent dust and breath pollution. For example, "Book of Rites" records: "Cover your mouth for fear that your breath will touch others." And "Mencius Li Lou" records: "Xizi If it is unclean, everyone will cover their noses and pass by."
