Mei Chaofeng wanted Quanzhen neigong, why not learn it from Yang Kang?

[Tian Chixing's Chef]

So Mei Chaofeng wanted to trick Ma Yu into teaching her his Quanzhen internal power method, but he recognized her intent and stopped short after sharing a small portion of it.

However, since Mei was Yang Kang's teacher, and Yang Kang learned exactly the same internal power as Guo Jing did through his other teacher Qiu, why didn't Mei ask Yang Kang to share the Quanzhen method with her?

If Mei asked, do you think Yang would acquiesce? He seems more fond of teacher Mei than teacher Qiu.

[Western Eccentric]

I think Yang Kang knowledge about Quanzhen neigong too shallow or perhaps Qiu Chuji didn't dedicated teach him like Ma Yu did when he taught Guo Jing about Quanzhen neigong other reason is Mei Chaofeng is Yang Kang secret "teacher" so they might be didn't have enough time to "teach" each other..
