Second, the founder of Quanjude is Yang, who buys and sells raw chickens and ducks in the meat market street outside Qianmen. This man is clever and capable. In the early days of Quanjude, he found an old chef Sun who made royal roast duck for the court, made great efforts to make friends with him, and hired him to Quanjude with a large sum of money, thus mastering all the techniques of hanging roast duck in Qing Palace. Third, Quanjude can become a famous restaurant, the primary reason is that the materials are solid and the chefs are skilled. Quanjude's roast duck is roasted by secret recipe, hanging stove and fruit tree. Ducks are beautiful in appearance, full and full, bright in color, bordeaux in color, crispy in skin and tender in meat, delicious and crisp, fat but not greasy, thin but not firewood.
