The secret of this difficult Xiangqi formation lies in the Red Rook's exposure on ranks 10 and 2, the two Red Cannons' exposure on rank 7 and file 3, and the Red Pawn's exposure on rank 5. This creates an iron net, rendering the Black Rook on rank 5 and the Black Horse on rank 8 powerless. The Red Cannon on file 3 will be the key to 'shooting' the Black Pawn on rank 5, opening the way for the Red Rook's attack.
