@AbraarKaran @happyhexer I've NEVER seen a mask brace in actual use. Until and unless those are widely distributed and there is effective public eduction, probably best to not even bring that up.
KN95/N95/KF94, sure. Those are out there, maybe get people to switch. Even just surgical is better.
@AbraarKaran@happyhexer我从未见过面具支架在实际使用中。除非这些信息被广泛传播，并有有效的公共教育，否则最好不要提出来。
KN95/N95/KF94，当然。这些都在外面，也许能让人们改变。即使只是外科手术也更好。
