A possibly male Rufous-bellied Niltava was seen near the junction for choosing red or blue walk.
I managed to see it for seconds by its fully uniform chestnut underpart from the breast to the vent. Hence, it is different from Fujian Niltava by its washed out lower part of belly and vent. Also, I can also see its black face and complete throat, so Vivid Niltava can be ruled out. For its sound, it is rather soft and is slightly different from Fujian Niltava.
By the way, i am not confident for Rufous-bellied Niltava because of weak light condition near darkness around five-forty. May be .... it is just a dark version of Fujian Niltava.
I also got one Verditer Flycatcher, one White's Thrush and many invisible thrushes on the red walk.
