Go to the group and ask parents what homework to leave. No one is embarrassed to answer.

This situation is really embarrassing, but don't worry too much. Maybe everyone was busy and didn't notice the news in the group. You can wait a little longer and see if any parents reply. If there is still no reply, you can consider the following methods:

1. Try to contact parents one by one: ask parents about their homework directly by telephone or individual communication. This can avoid the embarrassing situation that no one replies to the group news.

2. Check whether your homework is clear: make sure your homework is clear to avoid misunderstanding or confusion. If you are not sure about the specific content of the homework, you can refer to the textbook or related materials to ensure the correctness and consistency of the homework.

3. Share homework content: If parents still don't reply, consider posting homework content in the group to remind parents to check. This can reduce parents' doubts and help avoid embarrassing situations.

4. Pay attention to parents' feedback: If parents have any questions or suggestions about homework, please reply in time. This can establish a good communication relationship between home and school and increase parents' participation and satisfaction.

Most importantly, keep a good attitude and patience. Communication with parents needs to be based on mutual trust and understanding, so it is very important to maintain a positive attitude and patient communication.
