Time Out says
The Clan Jetties are unique Chinese settlements that have been around since the 19th century. Along the wooden pier are villages on stilts that house the descendants of Chinese immigrants. There are eight different clans that still reside here, with each individual jetty named after their surname. Likely the most tourist-friendly would be the Chew Jetty whose residents occupy the entire stretch of jetty. Today, these houses remain homes to a number of families , so request for permission from them before snapping photos there.
