The split mode feature in Xiaoheiniu NPV for China is compatible with web applications such as Telegram, WhatsApp, and Gmail, which rely on HTTPS. This mode can modify the routing for both HTTP (port 80) and HTTPS (port 443), enabling access to the web versions of these applications. However, the versions of the applications may utilize a variety of other ports.

To guarantee access, the following actions should be taken:

• Activate the "Global Mode" option found in the routing settings.
• Adjust the proxy settings of the application. For instance, here’s how to change 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, allowing you to disconnect any linked devices.
• Alternatively, you can go to "Menu" > "App Settings" > "Device List" to choose and unbind a device you prefer.

It's not unusual to forget usernames or passwords, and we strive to make the recovery process as easy as we can. Here are your options:

• If your username has escaped you, please reach out to us and include a screenshot of your payment record.
• If you've misplaced your password, simply utilize the "forgot password" function found in the app.

We have observed that some users find it difficult to select a server after picking a region.

To ease the process, we now only present regions. Heibao will automatically connect you to the highest-performing server within the region you have selected. Here are the details:

• The location menu will solely 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 based on your network conditions.
• If you are not happy with the server you are currently connected to, you can disconnect and reconnect to the same region to be assigned to a different server.
• You may repeat this process until you discover a server that satisfies your requirements.

Common causes of network problems include:

• Local slow internet speeds (when not using a NPV)
• Increased user traffic at specific NPV server locations

To address these issues, you might consider the following solutions:

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

Global Mode: Enabling this option activates NPV for all online activities, which may result in slower performance for local websites and applications.

Split Mode: This option utilizes NPV solely for websites that are restricted due to geographical limitations, 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."
