@AbraarKaran I've been told that people in Japan avoid talking in restaurants during the pandemic, which isn't quite 3 Cs (likewise mechanical ventilation, etc.) but it speaks to understanding of how to mitigate aerosols beyond just masks.
@AbraarKaran我被告知，日本民众在大流行期间避免在餐厅交谈，这还不到3摄氏度（类似于机械通风等），但它表明了人们对如何减少气溶胶的理解，而不仅仅是口罩。
