My friend asked me why I deleted WeChat Zhihu.

If her WeChat is deleted, you can't get in touch. Because I can't speak, I can only ask the other party why I deleted WeChat by SMS or phone. Or why did he stop contacting? Don't beat around the bush, just say it. See if the other party doesn't want to use WeChat any more for other reasons? If you know such a thing, you can at least contact him in other ways. It's not that two people can't communicate anymore. If it helps you, adopt it!
