In the year 1905 AD, a new station was to be developed on the western-outskirts of Beijing in order to connect to the City of Zhangjiakou (Kalgan) someways North-West out of Beijing on the Great Wall of China in Hebei Province.
In the Past a river had flowed from the western hills into Beijing through the (vicinity of) Xizhimen Gate, however there was no place for both the River and a Railway Station. Thus, the historic Chang He (Chang River) Section near Xizhimen - known as the ZhuanHe for its curvature - was filled in and its course changed. Although the original Chang He River does not exist anymore and Xizhimen has meanwhile grown into the Beijing North Railroad, Subway and Bus Station, the River gained a new life in 2003 AD.
Find the current River flowing some ways to the North behind Beijing Zoo in the eastward direction. Somewhere in the next stretch it tunnels underground beneath the highways of Beijing's Second Ring Road, after which it reappears above ground just West of Deshengmen Gate. After passing Deshengmen in the shape of a concrete canal its name changes to Andingmen XiBin, the waters running along the North Section of the 2nd ring road to flow past Andingmen and just North of the YongHeGong - Lama Temple. Go North of the Lama Temple and pass underneath the second ring road to find the Water Flow and Canal again.
