Nanjing’s metro will be officially opened soon, and it has already been opened for “sightseeing” – you can buy an expensive ticket for a one-time trip. Look at the photos below, does it look like Hong Kong’s MTR station? But I can’t find any relationship between MTRC of Hong Kong and Nanjing’s metro company. Copycat of metro station design, maybe?
南京地铁瞒恶心的，到目前为止，还没搞定 地铁内手机信号问题。
It is said MTR is copying their system to every metro in mainland China.
