Wear a mask, especially in public places and confined spaces with poor ventilation.

Wash your hands before wearing a mask. Wash your hands before and after taking off your mask. Fold the mask inward and throw it into the trash can. Before wearing a mask, you should distinguish between positive and negative. Face the nose clip of the mask upward and the dark face outward. When wearing the mask, put your fingers in the middle of the metal nose clip, press inward, and move your fingertips along both sides of the nose clip until the nose clip is completely pressed into the shape of a bridge of the nose. Check whether air leaks from the edge of the mask, including the nose. Adjust the nose clip. When sneezing or coughing, you don't need to take off the mask and change it in time.
