The game server latency is too high

In China, no matter which server you connect to, it's extremely laggy and unplayable. There's no way to have fun at all!
The latency of the Hong Kong server is 452 milliseconds, that of the Japanese server is 378 milliseconds, and that of the Singapore server is 412 milliseconds. The latency of other servers is also too high, with the highest reaching 550 milliseconds!
Could you please optimize the Hong Kong server? Please help players solve this problem, official!
Please Jonathan！

it was okay for me for the past 2 months 10ms ~ 40ish ms (occasionally jumps, unplayable at peak hours), but the last 3 days, it started at 40ms and jumps to 150ms whenever i move and stayed 150ms. it was never like this before.
