Today is Christmas Eve, but the old man is on duty in the unit, a student who lives in the school suddenly vomits at night, the old man is busy dealing with this matter, and now he is done, he is physically and mentally exhausted, please take a leave tonight, and I have to go to the student dormitory to see the student's situation later, and please forgive me.

By the way, I wish you all a happy Christmas Eve! Thank you for your continued support!
