How to choose a V2Ray server region for Chinese users

For Server Provider is AWS Lightsail, Only 3 regions for Chinese users to select: Tokyo, Seoul, Singapore.

Only one choice, Seoul is the V2Ray server destination, no other selection, because Seoul is the nearest place for Chinese users, you can find the ping latency is below 100ms, average 80ms.

For Server Provider is AWS EC2 or Google Cloud, many choices for Chinese users to select: Hong Kong, Taiwan, Thailand, Singapore, Osaka, Tokyo, Seoul, and more.

If you stay in the north line of Hangzhou and Shanxi, you should select Seoul as your V2Ray server location.

If you stay in the south line of Hangzhou and Shanxi, you should select Hong Kong, Taiwan, or Thailand as your V2Ray server locations.

🌏 V2Ray Server Region Comparison for China Users

The best server choice depends on two main factors: the cloud provider (which dictates available regions) and your geographic location within China relative to the Hangzhou-Shanxi line.

Scenario / Provider	Recommended Regions	Key Characteristics & Latency (from China)	Use Case & Notes
1. AWS Lightsail (Limited Options)	Seoul (Only Choice)	Low Latency: Average ~80ms, often <100ms. Stability: Nearest optimal region to mainland China.	This is the only viable choice for Lightsail due to latency. Tokyo and Singapore are not recommended as they will be significantly slower .
2. AWS EC2 / Google Cloud (Many Options – General)	Hong Kong, Singapore, Tokyo, Seoul, etc.	Variable: Latency depends on the specific region and your location in China. Key Rule: Select based on the “Hangzhou-Shanxi” geographic line.	Best performance requires selecting the region that aligns with your physical location, as detailed in the two scenarios below.
2a. North of Hangzhou-Shanxi Line (e.g., Beijing)	Seoul	Lowest Latency for North: ~80ms. Optimized Route: Direct undersea cables from Korea to northern China.	This provides the most stable and fastest connection for users in the northern part of the country .
2b. South of Hangzhou-Shanxi Line (e.g., Guangzhou, Shanghai)	Hong Kong, Taiwan, Thailand	Lowest Latency for South: Hong Kong offers ~30-50ms . Premium Routing: Often uses direct CN2 GIA or optimized undersea cables.	Hong Kong is the top performer. Taiwan and Thailand are good alternatives with similarly optimized routes for southern China .

💡 Summary of Selection Strategy

If you must use AWS Lightsail: Your only good option is Seoul. Do not choose Tokyo or Singapore.
If you can use AWS EC2 or Google Cloud:
- Users north of the Hangzhou-Shanxi line (e.g., Beijing) will get the best performance from Seoul.
- Users south of the Hangzhou-Shanxi line (e.g., Shanghai, Guangzhou) will get the best performance from Hong Kong, followed by Taiwan or Thailand.
