High ping means delay and rubber-banding in game. Try these steps in order.
1. Pick a nearby region
From Myanmar, a Singapore or Tokyo route is usually best. A far region will always add ping.
2. Close background apps
Downloads, YouTube and cloud backups eat your bandwidth.
3. Fix your signal
If you are far from the router you will get packet loss. Use the 5GHz band if you have it.
4. Use a VPN if the route is unstable
Sometimes high ping is not about distance — it is a bad route. A VPN can give you a more stable path. Zilo VPN has locations such as Singapore and Tokyo, and you can switch with one tap.
5. Try a different protocol
Zilo VPN gives you both an Outline (Shadowsocks) key and a VLESS Reality key. If one feels slow, try the other.
