How to delete photos taken on WeChat?

During the use of WeChat, it will slowly occupy the memory of the mobile phone, especially when there are many photos, which will affect the speed of the mobile phone. There are two ways to delete these photos:

1, you can delete a single chat record. Some friends don't want to delete, so you can choose this method. There are many photos in the general group information. You can open the group, click the double-headed logo in the upper right corner, enter the chat information, and then turn to the bottom. There is a "clear chat history" that allows you to clear the photos inside.

2. You can clear the photos in the whole WeChat. Click "I" under WeChat, enter "Settings", and then click "General". Click "Empty WeChat storage space" or click "Chat record migration". The former can't be retrieved after the photo is cleared, and the latter can be retrieved.
