Removing Chinese apps on Beta Firmware

So I found this video of how to remove chinese language and apps from the beta firmware. I think it’s in Russian and I don’t understand a thing. Can someone explain what’s going on and is it safe to do what the guy is doing in the video… Here’s the video link.

He removes files trough ADB. Is it safe? No, or depends on what he’s actually removing. Cant say for sure without knowing that. If you want an other not safe way to remove stuff, see my list on https://meizufans.eu/forum/topic/3372/request-list-of-system-apps-that-can-be-removed-titanium-backup
