The inquiry website shows that the Education Bureau does not go to work on weekends. The Education Bureau belongs to the state organs, and the state organs in China implement unified working hours, with Saturday and Sunday as weekly rest days. Therefore, if you go to the Education Bureau on weekends, you may encounter the situation of not opening the door, but you still can't solve the problem. Here, I suggest you contact the high school teacher first. If it is urgent, it is more useful to contact the relevant departments through the school than to go to the Education Bureau by yourself.
