I would like to ask you for a leave of absence, the reason I think students and friends understand, there are only two weeks before the exam, I have to prepare for review, during the update as fate as I like, I may occasionally change a chapter when I am bored, and it will last until the last exam is completed on January 11, and it will resume to a daily update during the winter vacation.

"Control the muscles" leave note is in the hand, please wait a while,
