Despite the obscurity of white crescent on the chest, this bird was much larger than a Bluetail in the field, with body proportions fitting the larger Niltavas. Also someone has taken shots of presumably the same bird last week showing the white crescent on her chest, normally obscured when her feathers are fluffed up:

This bird seems to be the female Niltava that has been sighted around the same spot in picnic area one for around 2 weeks already, and was variously considered as Fujian, Rufous-bellied or Vivid Niltavas by different birdwatchers, but none seems to fit the description perfectly.
Could this be a Rufous-bellied Niltava based on the lack of whitish belly shown by most female-type Fujian? The lack of obvious white cresent also seems to befit Rufous-bellied more than Fujian from the limited number of photos online.
Cheers,
Koel
