It was too quick that i couldn't take a photo of it.
But black and yellow stripes, green upperparts, golden underparts, black upper bill and light yellowish under bill were clear.
In addition, It's call was like two short high note (bi-bi), followed by around 6 lower but quicker note (the former three are slower and the later three are quicker).
I'm not sure if there are other warblers' call like this but i hope it helps to identify.
