土瓜灣
At initial stage, Sung Wong Toi station was named as To Kwa Wan station, while To Kwa Wan station was named as Ma Tau Wai station. Yet, such naming did not please adjacent community as geographically former To Kwa Wan station was not recognised as part of To Kwa Wan. Therefore, MTR internally amended the naming but had not been revealed to public until 2017 Panel on Transport of Legislative Council.
