The split mode feature in Tudou NPV for China is compatible with web applications such as Telegram, WhatsApp, and Gmail, which operate over HTTPS. This mode can modify the routing for both HTTP (port 80) and HTTPS (port 443), making it easier to access the web versions of these applications. Nevertheless, the application versions might utilize different ports.

To guarantee access, the following steps should be taken:

• Select the "Global Mode" option found in the routing settings.
• Alter the proxy settings of the application. For instance, here’s how you can adjust the proxy settings for the LINE app:
  
  

• If you try to sign in on a new device and surpass the device limit, you will be directed to the "Unbind Device" page, allowing you to disconnect any linked devices.
• Additionally, you can go to "Menu" > "App Settings" > "Device List" to choose and unbind a device as you wish.

Forgetting usernames or passwords is a common occurrence, and we strive to make the recovery process as easy as we can. Here are your options:

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

To make things easier, 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 display only regions, but each region has hundreds of servers. When you choose a region, Heibao automatically connects you to the server that provides the best performance based on your network conditions.
• If you're unhappy with the server you're connected to, you can disconnect and reconnect to the same region to be associated with a different server.
• You can go through this process as many times as needed until you find a server that suits your requirements.

Frequent reasons for network problems consist of:

• Reduced internet speeds locally (without utilizing a NPV)
• Increased user traffic at specific NPV server locations

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

• Verify your local internet speed by temporarily turning off the NPV
• Experiment with various network connections such as WiFi, 4G, or 5G with the NPV disabled to detect any connectivity issues. For instance, if your WiFi connection is inconsistent, switch to a mobile data network.
• Disable the NPV, select a different server location, and then reconnect
• If you prefer to remain connected to the same geographic area, disconnect and reconnect, as this may link you to a different server within the same vicinity.
• Keep conducting these tests until you identify the most optimal server for your needs.

Global Mode: Enabling this option turns on NPV for all online activities, which might lead to slower performance for local websites and applications.

Split Mode: This option applies NPV solely to sites that are restricted due to geographical barriers, like Google, YouTube, and Netflix, while allowing access to local networks for Chinese sites.

You can modify the routing mode within the App Settings.

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