Liang Chengqiao returned to his hometown and came to the ancient village. Facing the dilapidated wooden arch corridor bridge, he hoped to repair the ancient bridge and develop cultural tourism study tours, letting traditional skills re-enter the public view. Old carpenter Dong Shouqiao insisted on the traditional woven wooden arch craftsmanship, unwilling to change the rules left by his ancestors. Through arguments, the two gradually understood each other and jointly completed the corridor bridge repair. Su Lang promoted the integration of exhibition and study tours, making the ancient bridge glow with new vitality, and finally realizing the combination of traditional protection and modern inheritance.
