Lailong Ancient Temple, a famous temple in northern Jiangsu, was built in the Ming Dynasty and has a history of nearly 600 years. There are many legendary stories about this ancient temple. After the death of the great Buddhist monk Randeng, his body became a dried corpse, which was enshrined in the temple by his disciples. In order to respect the master, the people set March 15, the birthday of Randeng, as the temple fair day of Lailong Temple. The dried corpse was burned and the temple was demolished during the "Cultural Revolution" in 1964, and the temple fair was suspended for a time. In 2005, the abbot of Lingshan Temple in Dongyang, Zhejiang, Shi Gangru, responded to the initiative of the public and funded the restoration and reconstruction of Lailong Temple (renamed Lailong Ancient Temple) in the west of Lailong Town. The hall for the worship of Master Randeng and the walls of the wing rooms were built, and the construction of the main hall and other temples began. In 2007, the abbot of Zhangjiagang Xiangshan Temple, Master Fachan, continued to build the main hall and completed it. Later, Longgu Temple began to restore the construction, and the scale was gradually expanding. On March 15, 2006, the temple fair of Lailong Temple was officially restored. In the early days, the temple fair was only a grand sacrificial activity. With the development of the economy and the need for people to communicate, the temple fair gradually integrated into the market trading activities while maintaining the sacrificial activities. At this time, the temple fair was also named "temple market" and became an important form of market. With the needs of people, entertainment activities were added to the temple fair. So visiting the temple fair during the Spring Festival became an indispensable part of the New Year. However, the specific content of the temple fairs in various regions is slightly different and has its own characteristics.
