I want to ask how to delete WeChat in both directions.

In WeChat, two-way deletion means that both you and the other party can delete the chat record. The following is the method to realize two-way deletion in WeChat:

Single message deletion: in the chat interface, press and hold the message to be deleted, and then select the "Delete" option. This will delete the messages you sent or received. The other party can also do the same thing to delete the message.

Delete the mass message: in the chat interface, click the+icon in the upper right corner, and then select Multiple Selection. Next, select multiple messages to delete, and then click the "Delete" button at the bottom. This will delete the message you selected. Similarly, the other party can also delete the message of their choice.

Please note that two-way deletion only applies to messages deleted by both you and the other party. If only one party deletes the message, the other party can still see it. In addition, the deleted messages will only be deleted on your respective devices and will not affect each other's chat records.

In addition, WeChat also provides the option of "clearing chat history", which can delete the whole chat history at one time. In the chat interface, click the "+"icon in the upper right corner, then select "Settings" and then select "Clear Chat History". This will delete all the chat records between you and the other party.

It should be noted that the deleted message is unrecoverable, please consider it carefully before deleting it.
