Challenge: Red's Offensive: Black's Elephant is Forced to Retreat, Black's Rook on File 7 is Waiting for a Killing Move! - Can you solve it?

This Xiangqi position has a clear weakness at the rook on file 7. When Red launches an attack, Black's rook will be 'forced to retreat' immediately. This is a golden opportunity for Red's bishop on file 4 to deliver a killing move, sealing the game in one move.
