In 1907, Zheng Xingwen, the founder of the "old Chef", went to Harbin from Beijing to become the chief chef of the Yamen of Binjiang pass. He created the unique style of "blending north and south, combining Chinese and Western" in Harbin, known as "Binjiang cuisine ancestor". So far, it has been handed down to the fourth generation, and the "old kitchen" has also won the titles of Longjiang time-honored brand, Heilongjiang cuisine family, provincial intangible cultural heritage and Harbin Intangible Cultural Heritage Representative inheritor.
