First of all, I would like to introduce myself briefly. I come from China, a country recovering from the new pneumonia.Many of you
may have thought the same thing I did in the beginning, but you don't think so.But that has been proved wrong.This disaster is
actually unprecedented and quite terrible.
The mask developed by our company has three layers and its filtration performance reaches 97.5%, which is in line with
international certification standards.Don't think this is such a humble mask, it may be the straw to save your lives.The world is
one big family, we are together.
