Challenge: Xiangqi: The Red Chariot's Siege of the Black Cannon - The 'Bạch Đằng' Scenario on the Board - Can you solve it?

When the Red Chariot at 9/9 and the Red Chariot at 5/6 coordinate, the Black Cannon at 4/8 is trapped like General Tôn Thất Dũng in the Battle of Bạch Đằng. The Red Pawn at 4/6 blocks the cannon's escape, creating a classic 'double horse leg' formation. The Black General at 4/10 must think like King Lê Lợi before facing an invasion.
