At the end of January 2020, China's domestic epidemic broke out. Masks and other epidemic prevention materials were in short supply. Our company actively responds to the national call and resolutely helps to fight the epidemic prevention and control. We expanded new production lines to produce disposable protective face mask and KN95 face masks. We create what we need for a war epidemic. What our country needs is what we have to do. In early March, the domestic epidemic situation has been brought under control with our joint efforts, and we have seen the dawn of victory. But at the same time, the overseas coronavirus broke out. After our masks obtained CE and FDA certification, we began to lend a helping hand to overseas countries. This move has won unanimous praise from our government and overseas friends. Our original intention is to solve the current shortage of masks for international friends and work together to overcome the difficulties.
