South of the Yangtze, the landscape is more rugged. Like Shanxi Province to the north, Hunan and Jiangxi each have a provincial core in a river basin that is surrounded by mountains. The Wuling range separates Guizhou from Hunan. The Luoxiao and Jinggang divide Hunan from Jiangxi, which is separated from Fujian by the Wuyi Mountains. The southeast coastal provinces, Zhejiang, Fujian and Guangdong, have rugged coasts, with pockets of lowland and mountainous interior. The Nanling, an east-west mountain range across northern Guangdong, seals off Hunan and Jiangxi from Guangdong.
