First of all, see if it's the reason why your network cable is slow. Sometimes the network speed is slow and the loading is incomplete, which will also happen to you.
If the internet speed is ok, it's only when Hi is on. You can clean it up with 360 security guards.
Download system garbage, history, cache, etc. Finally, completely repair the system, and then open the browser to log in to the webpage Hi to try.
If not, it may be a browser problem. You can switch to other browsers, such as OPREA browser, Window of the World browser, Google browser and so on.
If all the above methods have been tried or failed, in order to avoid missing Hi messages, I suggest you use the client and download Hi. Go and use it.
