This particular ring is the former terminus of trolleybus route 13 partial. The partial route was created in 2010 due to extension of route 13 to Zhongshan Park using diesel buses; it was cancelled in 2016. Since then, trolleybuses have not used this terminus and the junction at Wanduhe Road / Changning Road leading to this terminus was removed.

Nowadays, route 13 is an electric bus route. Between 2014 and 2022, it was operated again with Youngman trolleybuses.
