It is a day on which the final resting places of one’s family ancestors are swept clean and sacrifices are offered for the souls of the departed. As people always go out on excursions on this day, it is also called the Spring Outing Day. Qingming Festival falls around April 5 on the Gregorian calendar, about a fortnight after the Spring Equinox.展开更多

Let’s see what benefits spring outing brings about and then pay attention to some matters while taking a trip out in spring. Benefits of spring outing Spring outing is especially popular with children and teenagers.But many adults also like to go on spring trips.The reason might be that spring outing can have several benefits.展开更多
