You can use it. You can buy it in a regular way. Xiantao is one of the largest mask producers in China. The requisitioned masks are mainly medical surgical masks and n95 masks for front-line use.

before, the production capacity didn't rise, and even ordinary disposable masks were provided to government departments, which made it necessary to resume the second and third line demand of enterprises.

a mask is a sanitary product, which generally refers to a device worn on the nose and mouth to filter the air entering the nose and mouth, so as to prevent harmful gases, smells and droplets from entering and leaving the wearer's nose and mouth. It is made of gauze or paper.

The mask has a certain filtering effect on the air entering the lungs. Wearing a mask has a very good effect when respiratory infectious diseases are prevalent and when working in a polluted environment such as dust.

at the beginning of the 3rd century, masks only appeared in China court. The waiter used a towel made of silk and gold thread to make a mask to prevent his breath from spreading to the emperor's food.
