When looking at the Shang Boulder, find the long thin diagonal crack/seam mid-face. The right portion (above Shanghai Knight v6 is a massive crack/jug/shelf, but as you follow the crack down and left it becomes a tiny, thin, feint crimp seam for the start) Follow this to its left end to find the start.
The left hand crimp has a "good" two finger pockety crimp portion, the right hand is an undercling/sidepull and is right facing.
This is a stand start.
Pull on and explode out right to the gaston crimp rail, and traverse through the crack to the right link into and finish as per "Shanghai Knight".
