Challenge: The Subtle Trap: The Double Horse Interlocking Formation in Xiangqi - Warning: A Move That Costs Lives - Can you solve it?

This board features a double horse interlocking formation, with the Red Chariot on file 5 and the Black Horse on file 7, rank 6. The Red side must be wary of the Black Cannon's 'sky-piercing' move on file 1, rank 4, while the Black side should be cautious of the Red Chariot's 'ambush' on file 7, rank 2. This is a secret formation from the 'Chess King' of the past century, now presented as a numbered trap.
