Guilin is a prefecture-level city in the northeast of the Guangxi Zhuang Autonomous Region of far southern China, sitting on the West Bank of the Li River. Its name means "forest of Sweet Osmanthus", owing to the large number of fragrant Sweet Osmanthus trees located in the city. The city has long been renowned for its unique scenery. In 314 BC, a small settlement was established along the banks of the Li River. In 111 BC, during the reign of Emperor Wu of the Han Dynasty, Shi An County was established, which could be regarded as the beginning of the city. In 507 AD, the town was renamed Guizhou.
