I don't know if this is known, but Shang stays morphed for as long as you hold block. More so, you can be pressing block repeatedly, duck block or dash block and still remain morphed. While dash blocking you get a free jump and if you're pressing block you can do any attack-combo. The jump is good because you can't morph back into Shang until you land and so you get a free air attack depending on who you're morphed in. Same thing for the combos after a dash block which can be canceled into specials before morphing (Skarlet's f2121+2 comes to mind). Using this you can fish for an attack without worrying about the timing when you may morph back.
