Dang, this answer, even adopted, there is a solution.

Modify the HOSTS file, manually add the overseas IP address

After modifying the HOSTS according to the tutorial, and then in the download of an origin CDN switching tool, select the recommended column, and then the network speed directly from the 1 kilobyte per second into 3.4MB per second ！！！！

To put it bluntly, it's just crappy oranges putting a wall around the country, so this shit is slowing down to a dog.

There's also a safe mode under rotten orange, turn safe mode off and you can still speed up by about 1-2MB~
