Who knows the historical and cultural background of moon cakes? What kind of food culture tradition does it reflect in China?

Moon cakes have a long history in China. According to historical records, as early as the Yin and Zhou Dynasties, there was a kind of "Taishi cake" to commemorate Taishi Wenzhong, the "ancestor" of China moon cakes. Zhang Qian introduced sesame seeds and walnuts to the Western Regions in Han Dynasty, which added auxiliary materials for making moon cakes. At this time, a round cake filled with walnuts appeared, which was called "Hu cake". In the Tang Dynasty, people had bakers engaged in production, and pastry shops began to appear in Chang 'an, the capital. It is said that one Mid-Autumn Festival, when Tang Xuanzong and Yang Guifei enjoyed the moon and ate Hu Bing, Tang Xuanzong thought the name Hu Bing was not pleasant to listen to. Yang Guifei looked up at the bright moon, and her heart surged, and she came to "moon cakes" at hand. Since then, the name of "moon cake" has gradually spread among the people. Xi 'an Food and Beverage United Food Company has launched Qin Feng series, series and series of moon cakes, and its "Gufaqin Cake", "Han Cake" and "Datang Furong Cake" are even more unique, allowing you to feel the Chinese Millennium food culture from small moon cakes.
