You was at Kaohsiung Metro, which was Train Station in China

In the distance on a Platform, you could see one of the KRT Girls (who were mascots for the Station) and she was called Nana!

She was currently giving hugs to fellow Passengers, posing for pictures and giving some people special kisses. She mostly posed on her pictures by standing normally with her hand doing a peace sign, but she will sometimes wrap her arms around a Man's Arm
