Aerial photo taken on April 29, 2020 shows the Yellow Crane Tower, or Huanghelou, a landmark in Wuhan, central China's Hubei Province. As the impact of the COVID-19 pandemic wanes, Wuhan's landmark Yellow Crane Tower was partly reopened to public on Wednesday. For the time being, there is still a visitor number limit (300 tourists are allowed into the main building every half hour) and online booking is needed. (Xinhua/Xiao Yijiu)
