The pier standing in the waters of the Jiulong River, the second longest river in East China's Fujian province, is a part of the Fuzhou-Xiamen High Speed Railway, which is currently under construction. Local media has dubbed the pier "a key to happiness". The railway, traveling 277.42 kilometers from the provincial capital of Fuzhou to the beautiful island city of Xiamen, will be put into use in 2022. [Photo by Liu Mohan/Xinhua]
