Although the chef Chen was killed by Cixi and no one in the Chen family worked in the palace, the relationship between Chen and Wang did not break down. According to Mr. Wang Xifu, after the late Qing Dynasty and the Republic of China, most of the two generations studied cooking. In the past, many people in Building 8 and Hall 8 were relatives of Mr. Wang Lao. Wang's two brothers worked as cooks in Beijing Building 8 during the Republic of China. The Wangs have a family heirloom, an old passbook that has been yellowed, with the "employment records" of several generations of famous chefs in Wang Chen on it. There are all kinds of banquet menus copied on the passbook, including some royal banquet menus handed down by my grandfather, high-grade banquet menus recorded by Mr. Wang's father when he was a chef in Huixiantang, and banquet menus for Zhimeizhai. In addition, there are a lot of recipes and ingredients, making methods and tableware styles. The menu includes Beijing cuisine, Shandong cuisine and Gongting cuisine, which are extremely precious. According to Mr. Wang Xifu, this old passbook placed in the "box worship" was passed down from ancestors to grandparents, and grandparents passed it on to their parents, and it was accumulated and enriched from generation to generation. Before his death, his father gave it to his eldest brother Wang Xirong for safekeeping. A few years ago, eldest brother personally entrusted this heirloom to Mr. Wang.

Speaking of it, Mr. Wang Xifu himself is "old Beijing", but he is not a diligent person. Probably influenced by the family's "food culture" atmosphere since childhood, this scientist engaged in the research of three-dimensional imaging technology seems to be a master of traditional food culture. This old gentleman knows a lot about "imperial cuisine" because his grandfather works in the imperial chef.
