Nanjie Cun, for example, has an average monthly salary of $32 USD, but all housing, utilities, healthcare, education, public transport, basic furniture (tv, microwave, beds, chairs) are provided for free for all residents of all ages. Also, there's a stipend of free food: rice, flour, some vegetables and some seasonings. Beyond that, there are communal canteens which is under $0.40 for a meal, or free for pensioners.

But you also have other areas of the country where you only get free food and housing if you're unable to work or in an area without jobs.
