Hong Kong is well-known to be a busy country and there is traffic congestion all the time even when one drives. Hence, many celebrities choose to take train in order to avoid traffic congestion. On 19th September 2018, Nancy Wu (胡定欣) uploaded a live video clip of herself wearing black shades and taking train on Instagram. We can even hear the announcement about travelling to the Central direction and Nancy took a selfie in the train after that.
