We stayed at Tianchi Summer Lodge, a rather shabby holiday resort located within Jian Feng Ling. It was conveniently connected to the Ming Feng Gu Boardwalk, which proofed to be quite birdy. The area includes Tianchi, which is a central lake area, and the core reserve area which is the prime piece of woodland.
The wooden boardwalk at Ming Feng Gu was productive, although the constant low light conditions made it tough to bird. We saw a lot of Silver Pheasants in there, as well as two brief encounters with Hainan Hill Partridge.
Birding at the arboretum was difficult due to how overgrown it had gotten. It was also leech infested, so I wouldn't recommend people birding in there.
The walk towards the core area is connected with a forest track, it was easier to walk and was quite productive, we had a few large bird waves there, as well as a few encounters with Red-headed Trogons as well as Ratchet-tailed Treepies.
When there weren't much birds around, there were always the sceneries to take in as well as meeting the friendly locals there.
