Longhua street is the central area of the former Longhua ancient town, and its history can be traced back to the Three Kingdoms period. In the area where Longhua Ancient Town is located, the name "Longhua Dang" appeared in the Three Kingdoms period, and the name "Longhua Port" appeared in the Eastern Jin Dynasty. In the Tang Dynasty, Longhua area successively belonged to Xinyi, Kunshan and Huating counties. At this time, with the population reproduction and the continuous expansion of natural villages, Longhua market gradually formed. In the Five Dynasties, the name "Longhua Village" appeared. In the third year of Chengchun in the Southern Song Dynasty (1267), Shanghai Town was built; At the beginning of the Yuan Dynasty, Longhua had become an important post station on the ancient postal route, and the market had begun to take shape. In the Ming Dynasty, Longhua has built a very prosperous town, and Longhua Temple Fair has become famous. From the formation history, the history of Longhua ancient town is earlier than that of Shanghai. In the long process of the gradual development and prosperity of the ancient town, the traditional culture has been accumulated and precipitated, and has been fully developed. The profound traditional culture of Longhua Temple Fair is an important reason for its existence and development. This is also a universal law of the development of cultural matters: the more profound the cultural heritage, the greater its influence and the longer its existence. In addition, Longhua ancient town has a quite superior geographical environment. In the Ming Dynasty, Hua Gang, a one-stop train, crossed the town, connecting Huangpu River in the east and caohejing and Puhuitang in the west, which was the main waterway of Longhua Ancient Town. It is this main waterway that, on the one hand, connects the East China Sea through the Huangpu River, which facilitates the movement of people and goods from south to north. On the other hand, Longhua Port connects caohejing and Puhuitang, which provides convenient transportation between Longhua Ancient Town and other parts of Shanghai. Convenient and fast transportation, whether in agricultural society or industrial society, has an immeasurable impact on economic and cultural exchanges.
