The original site of the Blue House used to be a hospital. This two-story building is called "Huatuo Hospital". 1920 After the demolition, a four-story building was built with "Huatuo Temple" underground. The back of Huatuo Temple was replaced by a martial arts school opened by Huang Feihong disciple Lin Shirong's nephew Lin Zu. 1960s, Lin Zu's martial arts was changed to Yiguang of his sub-forest.
The walls of the stairwell and the windows in the unit are also made of wood, which is one of the few remaining Tang-style buildings with terrace buildings in Hong Kong.
