Where did Nanjing cuisine originate?

The standard name of Nanjing local cuisine is "Sujing Cuisine", that is, Nanjing local cuisine, also known as "Jinling Cuisine", which forms "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 site of Jiangsu Province in the Qing Dynasty. "Big food" is used to describe the preciousness, elegance, beauty and generosity of Nanjing cuisine. It is the land of fish and rice in the north and south of the Yangtze River that is rich in products, the exchange of land and water transportation and commerce, the influence of humanistic culture and exquisite folk customs that gave birth to Nanjing's gourmet culture. Qu Yuan, a patriotic poet in China, recorded many characteristics of Wu Chu cuisine in Chu Ci, including beef tendon, roast mutton, stewed turtle, stewed turtle, boiled swan and stewed duck. After Wu and Sun Quan made their capital Ye, the social economy developed rapidly. Jinling, as the largest commercial port in China, is crowded with distinguished guests. On both sides of Qinhuai River, the smoke from kitchen chimneys is curling up and the wine is mellow. The representative of Liu Chaotian's chef, Yu Yun of Nanqi, is good at seasoning, and the dishes he makes are delicious, which is better than the official meals in the palace. Li Yu, the leader of the late Southern Tang Dynasty, visited the banquet in Han Xizai and drew the famous Banquet in Han Xizai, which was a true portrayal of the Jinling 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: "The smoke cage is covered with gauze in the cold month, and Qinhuai is close to the restaurant at night." Wu's The Scholars was written with Jinling as the background. Li Bai, a great poet, visited Nanjing four times and wrote immortal poems such as "On the Phoenix Terrace in Nanjing". In the Song Dynasty, Wang Anshi built a mid-level garden at the foot of Zijin Mountain, lived in Jinling for decades, and wrote a generous and tragic masterpiece "Jinling Nostalgia". Yuan Mei, a talented scholar in the south of the Yangtze River in Qing Dynasty, wrote a famous work "Eating List with the Garden" in Nanjing Xiaocang. The book was published in the fifty-seventh year of Qing Qianlong (1792), and all of them are based on Beijing-Soviet cuisine. Cao Xueqin even provided an eloquent basis for Beijing-Suzhou cuisine to stand out in the whole country with the records of famous dishes in the famous novel A Dream of Red Mansions.
