Yanping Prince belief and customs venerate Zheng Chenggong, a national hero celebrated for his defense of China's territorial sovereignty. This folk tradition, deeply rooted in Zheng's hometown and regions of his influence, thrives in places like Xiamen and Quanzhou's Nan'an, where the Yanping Prince Temple serves as a focal point of worship.

Zheng, posthumously titled "Yanping Prince", has been deified over time. Following his death in 1662, numerous temples dedicated to him were established, elevating his status from a historical figure to a deity. The tradition involves reading eulogies, performing operas, and offering birthday tributes.

The tradition of Xiamen began in the late 19th century with the construction of the Yanping Prince Temple, which is a classic piece of architecture nestled in the hills of Siming district.

Under local government support, the tradition has flourished, with numerous temples and memorials emerging across Fujian and Taiwan. The Zheng Chenggong Cultural Festival, held in Xiamen, Nan'an, and Taiwan, has been a major event, attracting thousands annually. These festivals involve traditional Chinese cultural elements, such as parades and performances, and foster cross-Strait economic and cultural exchanges.

This tradition demonstrates how historical reverence transcends boundaries. Through shared rituals and collective memory, it maintains vital cultural connections between Fujian and Taiwan, promoting peaceful relations and unity.
