Because the school's network sometimes has problems, sometimes the update will be unstable, and then I can't send a notice here or something, so I'll send one today.

Now there is a serious code word every day, if there is no update on the day, and there is no notice to ask for leave, it can only mean that the school is out of order.

But what you owe will be made up later, I promise!

Thank you all for your collection and recommendation!
