How do parents send text messages when the university is on holiday?

Parents who take leave from university can send text messages as follows:

Dear teacher, hello, I am the parent of (child's name). (child's name) needs to take time off due to sudden illness. What leave instructions and procedures should be provided? I really appreciate it． Or dear dean/counselor, hello, I am the parent of (child's name). I hope (child's name) can take a week off for (leave reason). What certificates and procedures do you need me to provide?

When writing a leave message, you need to provide basic information such as the child's name, class, reason for leave, time for leave, and express your respect and gratitude to the teacher, as well as your concern and commitment to repay the progress of the class.
