On February 25, Ou Xiaoli, director of the Social Development Department of the National Development and Reform Commission, said at the press conference that not only should the supply of masks be increased, but also the scientific use of masks should be promoted. The demand for masks in this epidemic has exploded, which will inevitably cause the supply and demand sides to be unequal. It is unrealistic to reach the number of masks now, so it is scientific to use masks on demand and reduce unnecessary waste. At present, necessary. "Some people wear N95 when they live at home. Some people do not touch one or two people a day and change their masks for four hours. We think this is too rich and completely unnecessary. Here we call on everyone to do science While protecting yourself, you must shoulder the responsibility of using scientific masks sparingly. "(Editor Zhou Yi)
