Challenge: 'The Hidden Stone' on File 10: "Is Red preparing a 'stabbing' or a 'hidden cannon' in the shadows? - Can you solve it?

Behold this mysterious position as a traditional chess master would: "Red's army with three chariots and horses, Black's with two pawns and an elephant, standing like ancient gods on the board. Why is the Black Elephant revealed on File 10? Why does the Red Chariot stand as if 'waiting'? Let's uncover the secret of the impending 'surprise attack' when Red prepares to 'compel the use of the Chariot' to turn the tide. This is not just a lesson in tactics but a puzzle about the balance between offense and defense in Xiangqi."
