To attract people into the group, you must be friends first. At this point, WeChat acquiesces that you have this trust relationship. Then, especially for WeChat groups with less than 40 people, you can directly join the group without prompting, but groups with more than 40 people must obtain your verification consent, and then you have the right to choose not to accept the invitation.
First, open the WeChat application icon on the mobile phone desktop, enter the following page, and find the "I" button at the bottom of the menu bar. After entering the "Me" page, find the "Settings" button in the menu bar.
Then, on the settings page, find the "Privacy" button. Then in the next page, open the "Add me as a friend, need to verify" option, and then continue to click "Add my way".
Finally, enter the "Add my way" page, and turn off the function of which option without adding a way, so that strangers can't add friends casually and avoid being dragged into the WeChat group by strangers.
