The second phase of Guangzhou's Metro Line 7 spans 22 kilometers from Higher Education Mega Center South Station to Shuixi North Station. It will also incorporate the Shenjing, Changzhou, Hongshengsha, Yufengwei, Dashadong, Jitang, Jiazhuang, Kefeng Road, Luogang, and Shuixi stations. As of now, 38 percent of the section's civil engineering has been completed.

Once the second phase of Metro Line 7 comes into operation, Huangpu residents will be able to reach Guangzhou South Railway Station directly, or to transfer to the Pazhou feeder of the Guangzhou-Dongguan-Shenzhen Intercity Railway, the east extension line of Metro Line 8, or Metro Line 13, 5, 19, 6 and 21.

Construction of the second phase of Guangzhou's Metro Line 13 between Chaoyang and Yuzhou stations and the east extension line of Guangzhou's Metro Line 5 between Wenchong and Huangpu Passenger Port stations is also progressing. To date, 29 percent of the civil engineering of the former and 22 percent of that of the latter has been completed.
