How can parents send WeChat when they leave the teacher?

You can refer to the following template: Dear teacher: Hello! I'm a student's parent, and I want to ask you for leave in the name of a student. Please approve the specific reason and time period of leave. Leave time will allow children to study at home, complete the corresponding homework and learning tasks, and ensure that the learning progress will not be greatly affected. I hope you can approve it. Thank you very much for your understanding and support. Names and dates of parents.
