In the school classroom, the parent group message did not show the phone number of the parents, saying that the opposite side did not show where it was.

What you want to ask is the reason why the parents' phone number is not displayed in the news of the parents' group in the school class. It is said that it is not displayed on the opposite side. Privacy settings, group administrator settings.

1. Parents chose to hide the privacy setting of phone number in personal settings. This is done to protect personal information and privacy, and to prevent phone numbers from being abused or leaked.

2. The group administrator prohibits the display of telephone numbers in the settings. Is it out of consideration for the privacy of group members or to maintain a good communication environment?
