At 2,214 kilometers (about 1,376 miles) long, the Pearl River is the third largest river in China and the largest one in Guangzhou. It is so called because it contains a stone island resembling a huge pearl, polished by the constantly-flowing water of the river. Spanning eight provinces, the Pearl River is composed of four river systems including the West River, North River, East River and Liuxi River. The four river systems converge in Guangzhou and flow into the South China Sea. The Pearl River in Guangzhou City is picturesque, adorned by charming views along the river. A cruise along the Pearl River in Guangzhou City has become a must for visitors to Guangzhou. Whether you choose a daytime or an evening cruise, it will be a highlight of your trip.
