Yes, but it was called "Buff-bellied Flowerpecker" in HK as late as the 2005-2006 Bird Report. The entry in the 2007-2008 was a transitional "Fire-breasted (Buff-bellied) Flowerpecker" with just "Fire-breasted Flowerpecker" from 2009-2010 onwards.
The older editions of Viney - and it's not unusual for the people I take out birding to have one of the older editions - refer to the species as Buff-bellied.
