The split mode feature in Qingfeng NPV for China is compatible with web applications such as Telegram, WhatsApp, and Gmail, which make use of HTTPS. This mode can change the routing for both HTTP (port 80) and HTTPS (port 443), enabling access to the web versions of these applications. Nevertheless, the application versions may use different ports.

To guarantee access, the following steps should be taken:

• Utilize the "Global Mode" option found in the routing settings.
• Adjust the application's proxy settings. For instance, you can modify the proxy settings for the LINE app as follows:
  
  

• If you try to log in on a new device and surpass the device limit, you will be directed to the "Unbind Device" page, where you can eliminate any linked devices.

We've observed that some users find it challenging to select a server after choosing a region.

To streamline this process, we now only show regions. Heibao will automatically connect you to the top-performing server within your selected region. Here are the details:

• The location menu will exclusively display regions, but each region includes hundreds of servers. When you choose a region, Heibao automatically connects you to the server that delivers the best performance according to your network conditions.
• If you're not happy with the server you're connected to, you can disconnect and reconnect to the same region to be assigned to a different server.
• You can repeat this procedure until you discover a server that suits your requirements.

Frequent reasons for network problems include:

• Slow local internet speeds (without the use of a NPV)
• High user demand at specific NPV server locations

To address these issues, you can attempt the following strategies:

• Verify your local internet speed by temporarily turning off the NPV
• Experiment with various network connections such as WiFi, 4G, or 5G while the NPV is disabled to pinpoint any connection difficulties. For instance, if your WiFi connection is unstable, try switching to a mobile data connection.
• Disable the NPV, select a different server location, and then reconnect
• If you prefer to remain connected to the same geographic area, you can disconnect and reconnect to potentially connect to a different server in that region.
• Keep testing these options until you discover the most appropriate server for your needs.

Global Mode: This option enables NPV for all online activities, which may cause local websites and applications to load more slowly.

Split Mode: This option utilizes NPV only for websites that are blocked due to geographical limitations, such as Google, YouTube, and Netflix, while allowing access to local networks for Chinese websites.

You can modify the routing mode in the App Settings.

If you encounter difficulties accessing specific websites or apps, consider switching to "Global Mode."
