Back Kenpo:
Off a range 0 Feng DF1, back kenpo is hit by her 4, DF4 and 3, and so is quite limited. However, at further DF1 spacings it can make almost every move she has whiff.
Switch Stance:
Off the typical DF4 SWS entry, Feng's BF1 evades everything but SWS4 or crouch dash options, which CH him. However, Josie is only vulnerable for 14 frames if she does not do anything, and can launch BF1 on block.
