Challenge: Xiangqi: Defense Against Double Horse Legs, Black Cannon Stuck - AI Master's Solution - Can you solve it?

Red's double horse legs formation creates strong pressure. Black's cannon on file 1 is stuck on rank 6, and Black's chariot is on file 8, rank 5. Black's general on file 4 is in a 'disconnected space' situation, but there are sophisticated defenses like 'empty cannon' or 'chariot thrust' to counterattack.
