The specific operation process is as follows:
1. Open the QQapp on your mobile phone, click the contact, and then click the group chat to find the chat record.
2. After joining the group, click on the three bars in the upper right corner.
3. In the group chat settings, click Find Chat Records below.
4. Select the record you want to find. You can directly enter keyword search or search by category.
5. For example, if you want to find the chat history of a group member, click the group member and find the person you are looking for.
6. Then click on the speech you want to view that day, such as documents.
7. After clicking the record, you can see the file he sent.
