I think bok choy is rather thrown into a lot of Chinese dishes over here when really it's regarded as more of a sort-of soup vegetable. It'd be like putting cabbage in a full english.
One thing i've found is make sure you don't put the sesame oil in too soon, a lot of people tend to think sesame oil = cooking oil, though it's actually more of an additional flavour or seasoning, adding too early will make the sesame oil burn and give it a strange taste.
