Thanks ajohn a lot!
I agreed with ajohn that it was brown-flanked bush warbler.
It did make a few calls. The calls were weak and short. Just something like the call from combination of common tailorbird and dusky warble. I checked hbw.com for more bird calls, I found one which was similar to that bird.
As no adult bird around, no typical call and song of mountain tailorbird / brown-flanked bush warbler.
I have no idea of juvenile call. Should the calls same as adult bird call?
The underpart of the bird in photo is yellowish. This yellowish colour is similar to mountain tailor bird. (Although colour of juvenile can be very different from adult) The shape of the head is longer and slimmer than brown-flanked bush warbler.
The bill shape is not matched with mountain tailorbird(thin and long), but I cannot get a better photo to show a better angle.
The upper part shows brownish instead of greenish. Since the bird is photographed in a shadow of a bush and it is a juvenile, I am not sure about this.
The legs seems very strong in photo 1, but not in the other photos.
