Heukseok Station is a railway station on Line 9 of the Seoul Subway. Prior to the opening, this station was near to Chung-Ang University, but Sangdo Station in Line 7's subname was also Chung Ang Univ. So metro drivers and employers conferenced, and the result was deleting Sangdo Stn's subname. So now days, the subname 'Chung Ang Univ' is in Heukseok.
