The Qingming Festival (or Tomb Sweeping Day), which goes back 2,500 years, happens on April 4. This day falls on the first day of the fifth solar term of the traditional Chinese lunisolar calendar. Observed mainly by the Han Chinese and the Chitty people of Malaysia, it’s a time when people honor their ancestors through traditional food offerings and by sweeping tombs. Interestingly, this festival’s closely linked to farming as well. As temperatures rise and rainfall increases, Qingming is a sign for farmers to plant in spring.
