Go for an outing, also called spring outing, spring outing, etc. China's custom of going for an outing has a long history. Legend has it that it was formed as early as the pre-Qin period, and it was also said that it began in the Wei and Jin Dynasties. According to the Book of Jin, every spring, people go to the suburbs to enjoy the scenery together, especially in the Tang and Song Dynasties. Du Fu, a poet in the Tang Dynasty, once recorded the grand occasion of the royal spring outing: "On March 3, the world is new, and many beautiful women enjoy the cool in Chang 'an seaside." For thousands of years, outing has gradually become a ceremony, as if only by doing this ceremony can we really have spring. "I don't play in spring, but I am afraid I am an idiot." Bai Juyi's poem You Chun is a portrayal of this mentality.
