Introduction to the Chinese Valentine's Day: According to expert research, Yiyuan has the only rare landscape in China where legends correspond to real scenes and ancient architectural ruins exist - Zhinu Cave and Niulang Temple. The two are facing each other from east to west across the Yi River. The landscape pattern on both sides of the river echoes the "Altair-Milky Way-Vega" in the sky. They are strikingly similar, forming a unique landscape of the unity of heaven and man and the magic of heaven and earth. In order to carry forward our country's traditional culture, the Chinese (Yiyuan) Chinese Valentine's Day Couples' Festival has been held every year since 2008, with group weddings, blind dates and other activities held, which has become a favorite among lovers all over the world.
