Qing Ming Festival , falls on the first day of the fifth solar term, normal around 5th Apr each year. Its name denotes a time for people to go outside and enjoy the greenery of springtime (踏青 Tàqīng, "treading on the greenery") and tend to the graves of departed ones.
Also named Clear Bright Festival, Ancestors Day or Tomb Sweeping Day , Qingming Festival originated more than 2,500 years. Its origin is credited to the Tang Emperor Xuanzong in 732. Wealthy citizens in China were reportedly holding too many extravagant and ostentatiously expensive ceremonies in honour of their ancestors. Emperor Xuanzong, seeking to curb this practice, declared that respects could be formally paid at ancestors' graves only on Qingming. The observance of Qingming found a firm place in Chinese culture and continued uninterrupted for over two millennia.
