What is Su Dingfang?
{{one source|date=February 2022}} '''Su Dingfang''' ({{Lang-zh|t=|s=苏定方|p=|w=|first=|c=}}, 591–667) was a leading general of the [[Tang Dynasty]]. He won many battles. In 657 he destroyed the [[Western Turkic Khaganate]]. This expanded the Tang's western borders to their farthest extent (deep into [[Central Asia]], close to modern [[Iran]]).
