In October 2006, it was decided to rename three stations on Line 2 by the end of the year, adopting a new naming scheme: metro stations, unlike bus stops, are no longer supposed to be named after neighbouring vertical streets, but famous streets and sights in the vicinity, making it easier for visitors to find these places. The renamed stations are Century Avenue (formerly Dongfang Road), East Nanjing Road (formerly Middle Henan Road) and West Nanjing Road (formerly Shimen No. 1 Road).
