They have to ask the bathhouse worker to help them buy extra (额外的) time.“Its a fault in the system that you can not buy extra time on the ID card,” said Ren, a freshman in Wuhan University. The university is also considering some students suggestions that they may be allowed to pay after theyve finished the shower. But many stu
