Children serve just-cooked Jiaozi, a traditional Chinese dumpling, to the seniors who live alone during an event to celebrate the upcoming winter solstice at a community in Hefei City, east China's Anhui Province, Dec. 20, 2019. As the Winter Solstice or Dongzhi is drawing near, a celebrating event was held here to bring the children, seniors who live alone, and other residents of the community together to experience warmth of the neighborhood. Lots of Chinese people still observe the old tradition of having Jiaozi for dinner on the Winter Solstice. (Xinhua/Cao Li)
