Sai Ying Pun
On Mondays to Saturdays, there is an express service which roughly runs on the same route and labelled with 4X, which skips Sai Ying Pun on its outbound journey, and call at additional stops at the Central Ferry Piers and Central (Exchange Square) Bus Terminus. It also skips Sheung Wan and most of Sai Ying Pun on its return journey in morning peak hours.
