You can watch TV series on public ***WIFI and brush short videos. Just be careful not to do anything that will reveal private information.

Of course, if traffic supports it, it is still recommended to use traffic. After all, the public network is still not at ease, the security is not enough, and it is not smooth enough.

If the traffic is not allowed, use it, as long as it doesn't feel blocked. Be careful not to reveal your privacy. In the era of big data, once privacy is leaked, it is terrible. Just brush the video and watch the drama.
