China's new secondary school rules

China recently has encouraged certain rules in their secondary school to discourage "young love" among the students. "They must maintain a minimum distance of half a meter from each other at all times. In addition, boys and girls are not allowed to go around school premises in pairs." Are you serious? Honestly, I don't think the rule change is going to do anything but was it really necessary? But at the same time, I understand that parents and teachers want their students to work hard at school to better prepare them for the future, but what has changed that made them have the urge to enforce this rule? It beats me.
