Challenge: The 'Eight Palaces Formation' - When Defense Is the Art of Counterattack - Can you solve it?

In this formation, Black is like an experienced general, hiding behind a defensive shield resembling the Eight Palaces fortress, waiting for any opening to strike a decisive blow. Each Advisor and Elephant is not just a piece but a tactical arrangement as precise as Tang poetry – meticulous, symmetrical, and full of hidden meanings. Though Red advances with two powerful Chariots and Cannons, do not rejoice too soon, for behind the shield lies an ancient trap silently laid.
