Lecheng Temple is famous for a journey. Each year Hanxi Mazu leaves her temple and travels among the villages in a pilgrimage known as the Eighteen Villages procession. It began with a request. Farmers in Xializi, in what is now Wuri District, asked the temple to bring Mazu to their village to drive away the pests. The temple agreed. Neighboring settlements then began asking for visits of their own, and it became a yearly tradition. The pilgrimage lasts 22 days. It begins on the first day of the third lunar month, and the Mazu palanquin returns to Lecheng Temple on the twenty-second day. Followers then gather at the temple on the twenty-third day to celebrate Mazu's birthday. The route covers 10 districts of Taichung: Wuri, Dali, Taiping, Wufeng, East, South, West, North, Nantun and Beitun. Over the Qing dynasty, the Japanese colonial period and the Republic of China era, the form of the pilgrimage has gradually changed. On August 12, 2008, the Taichung City Government recognized it as intangible cultural heritage.
