Challenge: Xiangqi Super Hard: Defending Against the Red Cannon's Attack on the Black Chariot - Can you solve it?

When the Black Chariot is on File 5 and the Black General is on File 6, the Red Cannon on File 4 Rank 9 can 'fire' directly at the Black Chariot. However, with the Red Pawn blocking on File 6 Rank 9, countering requires such precise calculation that it's like 'playing Xiangqi against a super-hard AI'.
