A grand ceremony for paying tribute to Huangdi, or the Yellow Emperor, considered one of the common ancestors of all Chinese, is held at the Mausoleum of the Yellow Emperor on Qiaoshan Mountain, northwest China's Shaanxi Province, on Qingming Festival, or Tomb-Sweeping Day, which falls on April 5 this year. The day is an occasion to remember ancestors and deceased family members by visiting their graves. Spring outings are also a traditional part of the festival.
