I don't share the optimism here at all unless two things change:

1) end of centralized quarantine. Centralized quarantine means there is limit in the numbers of passengers that can enter. Decreasing from 14 days to 7 days means they could accept double the passenger with same facilities, (they might still need more staff processing the additional passengers)

2) end the circuit breaker rule. You can't plan trips if half the flights are cancelled due to prior passengers being tested positive. Unless you plan to be in China for several weeks or have very deep pockets to buy multiple times tickets, it is not worth the risk.

As we seen the COVID cases in Taiwan spike even with their strict entrance restrictions still in place, I don't think China will change their stance much as they have staked too much political points on keeping COVID out.
