National Treasure

In the northeastern corner of Tianjin's old Dongmen Alley, Li Banyeye, a direct descendant of a grand eunuch whom the neighbors loved to poke fun at over tea, was nothing more than a local rascal. Then one day, an old friend of his father, Li the Blind, suddenly came to visit. An imperial folding fan personally inscribed by the Qianlong Emperor, an unsigned memorial tablet... A series of mysteries began to unfold, and long-buried stories of the Four Generals of old Tianjin gradually came to light.
