Urban mass transit information update
The article mentions that Guangzhou has 13 lines, but after the opening of Line 18 on September 28, 2021, Guangzhou Metro will have 15 operating routes with a total length of 589.4 kilometers. I think it needs to be updated. — Yujun Chen (talk) 15:39, 29 January 2022 (UTC)
