Though, me also not much familiar and have not been there, I think this is the same place.Banjyang means centre where people can gather from 4/5 VDC's for their livelihoods and financial activities. As I know in Galyang Banjyang peoples of Chapakot,Tulsibanjyang,Pelakot VDC and some villages of Palpa easily can gather to access the Sunauli-Pokhara Highway and there is small bazar at Bhanjayng.For your further information this is the place where Andhikhola Hydro Power Plant located (5.1 Megawatt) and as I heard there are two Galyang-Mathillo and Tallo.

Hope it meets amazing bro's jigyasa about Galyang
