the standard name of local dishes in Nanjing is "Beijing-Suzhou cuisine", that is, Nanjing local cuisine, also known as "Jinling cuisine", which forms the "Su cuisine" with Huaiyang cuisine, Suzhou cuisine and Xuhai cuisine. According to historical records, Beijing-Soviet cuisine appeared in Nanjing around the Qing Dynasty. The so-called "Beijing" means that Nanjing was the Kyoto of the Six Dynasties and the early Ming Dynasty; "Su" means that Nanjing was the meeting of Jiangsu Province in Qing Dynasty. "Big food" is used to describe the preciousness, elegance, beauty and generosity of Nanjing cuisine. It is the abundant products of the land of fish and rice in the north and south of the Yangtze River, the exchange of land and water transportation and commerce, the cultural edification of humanities and the exquisite folk customs that gave birth to Nanjing's gourmet culture. Qu Yuan, a patriotic poet in China, recorded a lot of features of Wu Chu dishes in Chu Ci, including beef tendon, barbecued lamb, stewed turtle, stewed turtle, boiled swan and stewed duck. After Wu and Sun Quan established Ye as their capital, the social economy developed rapidly at that time. As the largest commercial port in China, Jinling is a luxury guest, and on both sides of Qinhuai River, smoke from kitchen chimneys is curling, and wine is mellow and delicious. The representative of Liuchaotian Kitchen, Yu Yun of Nanqi, is good at seasoning, and the dishes he makes are very delicious, which is better than the official meals in the palace. Li Yu, the late leader of the Southern Tang Dynasty, sent Gu Hongzhong to inspect Han Xizai's banquet and drew the famous "Han Xizai's Banquet", which was a true portrayal of Jinling's family banquet at that time. During the Tang and Song Dynasties, the catering industry was in the ascendant. In Du Mu's poem "Bo Qinhuai", there is a sentence that "the smoke cage is cold and the moon is covered with yarn, and the Qinhuai is near the restaurant at night". Wu Jingzi's Scholars was written with Jinling as the background. Li Bai, a great poet, visited Nanjing four times and wrote immortal poems such as on climbing in nanjing to the terrace of phoenixes. In the Song Dynasty, Wang Anshi built a Mid-level Mountain Garden at the foot of Zijin Mountain, and lived in Jinling for decades, writing a generous and tragic masterpiece "Jinling Nostalgia". Yuan Mei, a talented scholar in the south of the Yangtze River in the Qing Dynasty, wrote a great cooking work "Menu with the Garden" in Xiaocang Mountain, Nanjing. The book was published in the 57th year of Qing Qianlong (1792), all of which were based on Beijing-Soviet cuisine. Cao Xueqin even provided an eloquent basis for Beijing-Soviet cuisine to stand out in the whole country with the record of the famous dishes in the masterpiece A Dream of Red Mansions.
