At the end of the year and the beginning of the year, Beijing opened a number of rail transit lines, of which the western section of Metro Line 11, also known as the "Winter Olympic Branch Line", is located in Shijingshan District, from The Mokou Station in the north to the New Shougang Station in the south, with a length of 4.2 kilometers. There are only 4 stops on the Winter Olympics branch line, each of which has a long history and many stories.
