Quanjude, as a family business, is run by his descendants. Fortunately, the descendants of Yang Quanren took over Quanjude and still worked hard to make Quanjude famous, so that Quanjude was not eliminated by the times.

As the reputation of "the king of roast duck" spread further and further, Quanjude began to expand its scale nationwide, spreading branches and leaves, so that diners from all over the country could eat authentic Quanjude roast duck without going to Beijing.
