Xinhua photos of the day

Photo taken on Nov. 21, 2019 shows the Opera House covered in smoke in Sydney, Australia. Sydney's normally picturesque skyline was once again blanketed by thick smoke on Thursday, as around 50 bushfires continued to burn across Australia's east coast. Deemed "hazardous" by the New South Wales (NSW) State Department of Environment, health authorities have urged schools to keep children indoors during lunch breaks. (Xinhua/Bai Xuefei)
