Residual Pulse

The true family history of three generations of the Yu family in Shandong. Yu Jingzhi, a 12-year-old farm boy, broke into the county town alone with a steamed bun in his pocket. He started as a kitchen boy. With his unique skills and extraordinary courage, he started from scratch in troubled times and established the number one restaurant "Ludong Hotel", turning a small family from a humble family into a well-known local family. As the times surged, his six sons embarked on completely different lives: some joined the army and made meritorious deeds, some joined the revolution, and some faced the ultimate tear between blood ties and faith in the confrontation between the camps. Half a century of ups and downs, the ups and downs of the family, the separation and reunion of brothers, and the ups and downs of troubled times are all hidden in this endless family lineage.
