Quan Youzhi moved into the underground utility compartment in Beijing after her home in the eastern city of Shangqiu collapsed, the state-owned China Daily newspaper reports . She uses washrooms in nearby Lido Park, and quarrels with her husband who lives in a neighbouring hole. Hot water pipes keep the 9m square compartment warm in winter, but she has to stay above ground in summer when it gets too hot, or if rain causes it to flood. The 66-year-old, who collects empty bottles for a living, says she would like to rebuild her house but doesn't have the money.
