As the saying goes, "A teacher opens the door, but cultivation depends on the individual." Although others can practice the same Sword Control Skill, it's hard for them to achieve the accomplishments of Mei Guyu. Everyone must find the path that suits them best.
Take He Kao, for example; he has a special connection with the Crane-shaped Sword. If he combines it with the Moth Wings' utility, it could lead to a different kind of change. He is inevitably tempted, but he definitely can't practice it within his own yard.
The best place to train, of course, is the Floating Colors Grotto Heaven. If it were an ordinary day, he might have turned around and gone there. However, having just been reprimanded by Elder Li and at such a sensitive time, he restrains himself.
