The Gas Light Street with eighteen, nineteenth and twentieth steps and fifty-seven steps on the third floor is located at the end of Dudley Street. It is a very short, slightly steep uphill step road connecting Xuechang Street. All the steps are granite staircases. Four gas lamps stand at the four ends of the whole staircase road. The gas lamps are the only ones left in Hong Kong and have a long history. They were listed as the statutory monuments of Hong Kong on August 15, 1979. Dali Street is located in the south of Queen's Avenue, Central, Hong Kong. There is a downhill road from the west of St. John's Hall towards Central, and it is at the bottom of the slope. At present, the gas lamp turns on and off automatically from 6 p.m. to 6 a.m. We went there in the afternoon, without lights on and without artistic conception. Later in the afternoon, visit St. John's Hall and Hong Kong Concierge Hall, line up for the top of Taiping Mountain on the cable car; after the cable car goes down the hill, come back to Gaslight Street to see the night scene under the lights of the gas lamp, and then go along Snow Factory Street to Languifang. Gas Lantern Street, many Hong Kong TV plays, music films and movies take this place as a scene. It is a kind of happiness for me to watch Hong Kong movies in the Mainland when I was young, but now it is a kind of expression to visit small streets with Hong Kong's old feelings.
