The split mode functionality in Yinghu NPV for China accommodates web applications such as Telegram, WhatsApp, or Gmail that make use of HTTPS. This mode has the capability to change the routing for both HTTP (port 80) and HTTPS (port 443), enabling access to the web versions of these applications. Nevertheless, the different application versions may employ various other ports.

To guarantee access, the following actions should be taken:

• Utilize the "Global Mode" feature found in the routing settings.
• Adjust the proxy settings of the application. For instance, here’s how to modify the proxy settings for the LINE app:
  
  

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

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

To make things easier, we now only show regions. Heibao will automatically connect you to the server with the best performance in your selected region. Here are the details:

• The location menu will exclusively display regions, but each region includes hundreds of servers. When you pick a region, Heibao will automatically connect you to the server that delivers the best performance according to your network circumstances.
• 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 go through this process as many times as necessary until you find a server that suits your requirements.

Typical reasons for network problems include:

• Slow local internet speeds (without the use of an NPV)
• Increased user traffic at specific NPV server locations

To address these issues, consider trying the following approaches:

• Assess your local internet speed by temporarily turning off the NPV
• Experiment with different network connections, such as WiFi, 4G, or 5G while the NPV is disabled to pinpoint any connection issues. For instance, if your WiFi is inconsistent, switch to a mobile data connection.
• Disable the NPV, select a different server location, and then reconnect
• If you prefer to remain within the same geographical region, disconnect and reconnect, as this may connect you to another server in the same area.
• Keep conducting these tests until you identify the most appropriate server for your needs.

Global Mode: This option enables NPV for all online activities, which might result in slower performance for local websites and applications.

Split Mode: This setting applies NPV solely to sites that are restricted geographically, such as Google, YouTube, and Netflix, while allowing local network access for Chinese sites.

You can modify the routing mode in the App Settings.

If you experience difficulties accessing specific websites or applications, consider switching to "Global Mode."
