Can I lock the photo chat in the WeChat circle of friends?

Published photos are ok, but conversations without pictures (plain text) are not.

Open the WeChat circle of friends.

Click on your avatar in the lower right corner of the cover of WeChat to enter your personal photo album (space).

Find the photo you need to lock and open it.

Click on the 3 points in the upper right corner.

Select "Set as Private Photo" in the pop-up options.

If both pictures and plain text can be locked (set as private) before sending.

After editing the content/picture, before sending it, click "Who can see it", select "Private" and then send it.

I can't see it in my circle of friends after I send it. You need to click on the avatar to enter your personal photo album (space) to see it.
