Challenge: Xiangqi: The Surprise Strategy of the Red Rook and Cannon - Can you solve it?

When the Red Rook is exposed on File 7 and the Red Cannon is exposed on Rank 4, the position becomes fractured. This is the opportunity for the Red General to launch a surprise attack with 'Rook Retreat on File 4' combined with 'Cannon Advance on Rank 3' to create unexpected pressure.
