A young female film director follows the footsteps of her ancestors back to her hometown to trace her roots. In front of the ancestral grave with surviving tombstones, she hears a story from decades ago from the tomb guardian Tian Shun: Manager Yang Mingquan invited a Feng Shui master for his newly acquired Dejuquan Roast Duck Restaurant. The Feng Shui master said it was a place of geomantic omen, and as long as the old name of Dejuquan was reversed to Quanjude, it would surely prosper. Thus, Quanjude was born in Beijing. However, Manager Yang made an enemy of Hua Yingkui, the young master of Dejuquan. At that time, all roast duck restaurants across Beijing were making焖炉duck (roast in a closed oven). Yang Mingquan spared no expense to hire the famous imperial chefs Sun Tiegan and Wu Yishao. Sun Tiegan integrated the methods of roasting suckling pig from the royal court into the preparation of ducks, creating the incomparably fragrant and crispy hung-lung roast duck (roasted in an open oven). The reputation spread quickly, and Quanjude's business flourished.
