In 1941, in Tianjin, He Yan liquidated the "Hongyun Tower" mahjong parlor, which ostensibly provided entertainment for puppet traitors, but in reality secretly eavesdropped on intelligence. Senior Japanese and puppet officials sat at his card table and poured out secrets like tea - city defense deployment, rural clearing plans, and arrest lists, all became hidden cards in his hand.
He used "touch" to warn, "eat" to convey and withdraw, "kong" to give orders, and "hu" to report success. Nothing happened in three years.
Until Ichiro Yamamoto, the head of the Special Higher Education Course, sat down at the card table and played an east wind: "The east wind is blowing, and the undercurrent is coming. You think so, boss?"
He Yanqing touched Hongzhong and said, "Although the east wind is good, it is not as real as Hongzhong."
Yamamoto left with a smile, and the gray trench coat across the street was never changed again.
The cards are drawn and the secret war escalates. One hundred and thirty-six cards hide the future of a city, and every shuffle is a matter of life and death. When the action codename "Blooming on the Stick" sounded that night - there were a lot of cards in the room, who was playing, who was listening, and who was setting off the cannons?
