Challenge: The Xiangqi Formation Like White Sand: Black Defends Like a Silent Sword, Waiting for the Opportunity to Counterattack - Can you solve it?

A tense formation like a stretched string, where Black, despite being cornered, remains steadfast like Tôn Tử's ambush. Red advances pawns to open paths, cannons spin like swords, and chariots charge through the wind. But behind the fractured defense lies a thousandfold strategy waiting to erupt. This is not a battle of strength, but a test of will between stillness and motion, patience and explosion.
