My math is not wrong, using your few numbers. The bluster of “millions” - only 1 million for 1 day let’s assume - and 350 seats. That’s all. For 1 day it would take that many flights to reach here IF they were 100% filled with Chinese.
Spread it out some more, sure, for maybe 4 weeks.
It’s still alot to assume there are millions of Chinese who have come here. Let’s say you mean “2 million”, and it’s over 4 weeks.
That is 71k to 72k people PER DAY coming from China (direct OR indirect). Seriously, you think that many Chinese are coming in daily? Wow. I guess it’s possible, but not likely.
