The Sifang Road Public Toilet, a structure commonly known as a landmark on Dabao Island, traces its origins to the initial construction of four walled public toilets in Qingdao and Dabao Island in 1901. A significant improvement occurred in 1912 with the addition of a modern squat flush toilet on Sifang Road, part of a broader expansion where the total number of public toilets in Qingdao's urban area surged from 17 by 1922 to 32 by 1937, cementing this facility's role in the area's development and enduring popularity over the past century.
