Why is there high latency when playing Landlord overseas?

The main reason why Doudizhu is laggy when played abroad is that it is a mobile game developed by the game server in mainland China. The delay for mainland Doudizhu players is relatively low, but when playing games overseas, even with high-speed Wifi, the delay will be relatively high, the connection will be unstable, and the picture may freeze or even drift. Regarding the knowledge point of game network delay, generally speaking, the best state is that the delay is within 10ms, and the game can be played smoothly within 150ms, which basically does not affect the experience.

For mobile games like Doudizhu, the delay of more than 250ms is completely laggy, and may cause uncontrollable problems. How to speed up playing Doudizhu overseas? Is there any VPN suitable for connecting to Doudizhu domestic server? This Doudizhu is really toxic! I feel uncomfortable if I don't play it for a day! The best solution to speed up Doudizhu is to use a network accelerator. Through the virtual channel reverse VPN directly connected to the domestic server node, many intermediate links of network transmission are omitted, which can effectively reduce the delay and improve the game experience. Of course, your own network must be stable and fast enough to achieve the best effect.
