Yes and I've seen the transition happen before my eyes as i have visited China at least couple of times a year ever since the early 2010s till literally the weekend before the Pandemic blew up. I still remember the air pollution of old (which made me decide to NOT take up a role with a promotion offered to me there at one point as my family members are asthmatic) and how one of my direct reports there used to get continuous coughing bouts every winter and hasn't really had them in the last couple of years.
