A question regarding Cheung 3 Fung's relationship with his seven original disciples, the Mo Dong 7 Heroes.
Cheung 3 Fung evidently did not found the Mo Dong Sect until he was at a relatively advanced age. At the beginning of HSDS (proper, not including the flashback to Cheung Gwun Bo's youth at the Shaolin Temple), Cheung 3 Fung celebrated his 90th birthday, but the eldest of his students, Sung Yeun Kiu, was only in his thirties at most.
But did Cheung 3 Fung teach *and* raise his seven disciples from childhood? Their relationship was more familial (i.e. between father and sons) than the usual teacher/student relationships. Moreover, the disciples all had proper surnames (Cheung Chung Kai and Cheung Chui San shared the surname "Cheung" with their teacher, but that was just due to Cheung being a very common Chinese surname than any kind of biological or adoptive relationship)...suggesting that they had families (i.e. parents, not spouses or children, though Sung Yeun Kiu and Cheung Chui San naturally had their respective spouses and sons). So what was the deal? Did Cheung 3 Fung adopt seven orphan boys and raise them as well as train them? Or did the seven of them come from proper families and become Cheung 3 Fung's students through other circumstances?
