Aerial photo taken on Dec. 25, 2020 shows a noise barrier installed on the railway linking Beijing and Xiong'an New Area, in Bazhou, north China's Hebei Province. The Beijing-Xiong'an intercity railway opened to traffic on Sunday, connecting the Chinese capital with the country's "city of the future" -- the Xiong'an New Area. Located about 100 km southwest of Beijing, the Xiong'an New Area -- spanning the Rongcheng, Anxin, and Xiongxian counties and some adjacent areas-- is aimed at becoming a national model of high-quality development and a new engine for the modern economic system.
