The male homeroom teacher might be strict about management and such, but mostly it's just the initial burst of energy when taking on a new role. At first, he might be a little stricter, but eventually, things settle into a neglectful "hands-off" approach. As long as nothing major happens, he pretty much doesn't interfere.
But Li Weiwei, as a female homeroom teacher, is different. It would have been fine if she didn't manage the class well, but she's got this air of authority and manages the class meticulously. Even someone like Liu Jie, who usually acts like a campus bully, will pretend to be attentive during her classes, even if he's just putting on a show. It's the same when she's around checking classes; they straighten up immediately.
