Where is the cheapest place to live in Hong Kong?

Open studio in Causeway Bay, 5-minute subway station, 1 rent, 1 room 1 hall/balcony 1 rent, two people, 580 yuan/night, open studio with a big window. The room is simple in style, facing the famous Victoria Park, which looks green. The net area of the house is more than 40 square meters, which is a rare spacious place on Hong Kong Island. Definitely not the kind of wardrobe that pushes the door and gets into bed. Kitchen, bathroom and life balcony are all available, including drum washing machine, nespresso coffee machine and wireless network. The location of the house is very good. Walk to Tin Hau Subway Station for 5 minutes, walk to the Golden Business District of Times Square in Causeway Bay 10 minutes, and only 4 subways to Central, soho, Lan Kwai Fong and Tsim Sha Tsui.
