Plum Village also has a place in HK.
They, and the Korean Kwan Um are some of the few that do much in English, though.
Though the FGS centers have monastics that are English fluent.
(A couple of Tibetan centers in HK also do stuff in English, however.)
You could also inquire at HKU, Centre of Buddhist studies. <http://www.buddhism.hku.hk/>
Maybe ask if Ven. Prof. Hin Hung is doing anything.
The Centre, like the whole of HKU, operates in English.
