Challenge: Online Xiangqi: Red's 'Empty Cannon' Strategy in the 'Chariot Checkmate' Formation - Can you solve it?

Understand how Red uses the Empty Cannon to control the 3rd rank, forcing the Black Pawn on the 2nd rank to retreat, creating an Empty Cannon formation that compels the Black Chariot on the 6th file to retreat to the 9th rank, then unleashing the Chariot on the 1st file to checkmate the Black General. This strategy often wins when Black fails to defend in time.
