I presume you mean Shen Gaoren.

Anyway, for Gaoren, anvil hammer is your best friend. Just pund the legs untill he falls over, then smash the joint between the shell and body, aiming into the shell. You might bounce a bit here if your not on his left side, where it is most open. This is his weakpoint.

Using a lance makes this weakpoint easy to hit, and you can make him fall by attacking his body as well. Not reccomended though as he falls on you.
