Tianhe District is one of the eleven districts of Guangzhou, the capital of Guangdong province. In Chinese, the name Tianhe literally means "a river in the sky/heavens", which is also a Chinese name for the Milky Way. It is bordered by Yuexiu District on the west, Baiyun District on the north and Huangpu District on the east. Haizhu District is on its south, though they are separated by the Pearl River.

The Guangzhou Metro is the rapid transit system of the city of Guangzhou in the Guangdong Province of China. It is operated by the state-owned Guangzhou Metro Corporation and was the fourth metro system to be built in mainland China, after those of Beijing, Tianjin, and Shanghai.
