The "Grand Music Master of Spring Officials" in Zhouli mentions the Four Towns and the Five Mountains together. A town is a mountain that is the town of a certain area. Kuaiji Mountain is the town of Yangzhou, named Nanzhen. In the 14th year of Kaihuang in the Sui Dynasty (594), the Nanzhen Temple was built on the shade of Kuaiji Mountain. In the 14th year of Kaiyuan in the Tang Dynasty, the Four Towns were conferred the title of "Duke", and Kuaiji Nanzhen was called Yongxing Duke. The Song and Yuan dynasties conferred the titles of Yongji Wang and Zhaode Shunying Wang to Nanzhen respectively. In the early Ming Dynasty, the previous titles were abolished and only the god of Kuaiji Mountain was called. Emperor Kangxi of the Qing Dynasty sent officials to offer sacrifices 11 times and personally inscribed the plaque "Beautiful Belt Rocks and Valleys". Emperor Qianlong also sent officials to offer sacrifices 14 times and inscribed the plaque "Biaodian Nanjiang". At that time, the "Four Towns" were scheduled to have spring and autumn sacrifices, while the two southeastern towns mainly held spring sacrifices. The spring sacrifice of Nanzhen was scheduled on the sixth day of the third lunar month. As usual, the main officials of the provincial and prefectural levels presided over the sacrifice, and the county magistrates of Shanyin and Kuaiji accompanied the sacrifice. According to folklore in Shaoxing, the sixth day of the third lunar month is the day to offer sacrifices to the God of Kuaiji Mountain in Nanzhen. The ancients believed that the God of Kuaiji Mountain was the source of peace in the area, so villagers, pilgrims from Kuaiji Mountain, and tourists came one after another, numbering in the tens of thousands every day, and they were very pious to the mountain god. According to Shaoxing customs, once the spring festival ceremony in the second lunar month begins, the incense is as prosperous as that of Guanyin Bodhisattva on Xiangfeng Mountain. From the outside of the mountain gate of Yu Temple to the front of the Nanzhen Temple, it is nearly three li, and cloth tents and bamboo sheds are set up on both sides of the road, and thousands of merchants gather. There are teahouses, wine houses, restaurants, as well as silk, woolen fabrics, local and foreign cloth, various types of clothing, miscellaneous goods, daily necessities, bamboo and wooden toys, means of production, southern and northern fruits, fresh vegetables, and even farm animals and poultry all come to the "market". As for the stalls and small stalls selling wontons, noodles, Bobo tangtuan, mianbaba, plum cakes, fried shrimp cakes, crab cakes, shredded radish cakes, stinky tofu, sugar balls, peeled water chestnuts, fennel beans, and salted green beans, they are even more numerous. There are also groups of magicians, acrobats, selling martial arts plasters, cupping, wheelbarrow tooth extraction, grass-headed doctors selling herbal medicine, fortune-telling, divination, tooth worms, birds holding cards, etc. All kinds of people also flocked to the place. There are also monkey shows, shadow puppet shows, rap and selling pear paste candy, Shaoxing beach spring parrot singing group and other folk art performances on the open land. There are more than thousands of people of all kinds! Tourists crowded in front and behind, enjoying both the beauty of browsing and the convenience of shopping. On the river in front of the Yu Temple, painted boats, black-sailed boats, farm boats (uncovered wooden farm boats used by farmers to go out to work in the fields), and rowing boats, full of pilgrims and tourists, shuttle back and forth endlessly. There are no less than dozens of temple fairs in various parts of Shaoxing, and the Nanzhen Fair is the largest and most prosperous. In June 2006, it was included in the first batch of Shaoxing City's intangible cultural heritage list.
