I am confident that this is Buff-bellied Pipit Anthus (rubescens) japonicus. The prominent eye-ring, pale lores, large dark patch on the side of the throat, and fairly uniform grey mantle (albeit with darker centered feathers - but no pale "tramlines" c.f. Red-throated Pipit) are typical of this species, which now appears to be a regular winter visitor to Hong Kong. Long Valley is probably the best place to see it.
