We've observed that some users have difficulty selecting a server after choosing a region.
To make this easier, we now only show regions. Biubiu VPN for China will automatically connect you to the best-performing server within your chosen region. Here are the details:

• The location menu will display only regions, but each region includes hundreds of servers. When you select a region, Biubiu VPN for China automatically connects you to the server offering the best performance based on your network conditions.
• If you're unsatisfied with the server you're connected to, you can disconnect and reconnect to the same region to be linked to a different server.
• You can repeat this process until you find a server that meets your needs.

• Slow internet speeds locally (without using a VPN).
• High user traffic at certain VPN server locations.

To resolve these issues, you can try the following methods:

• Check your local internet speed by temporarily disabling the VPN.
• Test different network connections such as WiFi, 4G, or 5G with the VPN off to identify any connection problems. For example, if your WiFi is unreliable, switch to a mobile data connection.
• Turn off the VPN, switch to a new server location, and then reconnect.
• If you want to stay connected to the same geographical area, disconnect and reconnect as this could link you to a different server within the same region.
• Continue these tests until you find the most suitable server for your requirements.

• You can view your redeemed plans in the "My Account" section once you've redeemed your points.
• For a referral to be successful, your referred friend must download and start using the app. If they download but do not use the app, you will not receive your referral point until they begin using it.
