Cheng Beng (Qingming Festival), or Tomb-Sweeping Day, is a traditional Chinese festival falling around April 4th–5th dedicated to honoring ancestors. Families visit graveyards to clean tombs, offer food (like roast pork, fruits), and burn incense or joss paper (money, modern items) to ensure ancestors’ comfort in the afterlife. It is a vital, time-honored event for filial piety.
