This is a test if VPN will really help you to lower your ping, especially on Genshin Impact.
To me, this is the best option to improve your latency issue until Mihoyo has a server near your area.
Get a Starlink connection if available in your area, Pay for a VPN, or else increase your internet plan that you're currently using.

Half Yes, in some cases like purchasing prime gems.
