Qingming Festival, also Tomb-sweeping Day or Spring Outing Day, falls at the turn of mid-spring and late spring (usually falls on April 4 or April 5). Originated from beliefs and rites for ancestor-worshipping in spring, Qingming Festival is not only a solar term, but also a traditional festival. As a traditional major festival for ancestor-worshipping in spring, the festival is characterized by tomb-sweeping and ancestor-remembering which not only promote filial piety and family ties and awaken the common memory of the family, but also improve the cohesion and identity of family members and even the nation.
