I just want to emphasize that there is a clear distinction between temples (like Man Mo Temple mentioned by the OP, or the popular Wong Tai Sin Temple) and the Buddist Monasteries and Nunnery.

There are hardly any rules or prohibitions in the former only. Monasteries on the other hand each have their own rules. For example, no photos inside the main hall at Po Lin Monastery on Lantau, and no incense burning at Chi Lin Nunnery at Diamond Hill.
