It is not clear what the punishment is should a third fly be found in a lavatory.
The new rules, set by the Beijing Municipal Commission of City Administration and Environment, also include standards on odour, demands for the number of pieces of discarded rubbish – no more than two – and that discarded items should not be left for more than half an hour.
The guidelines include an advisory on exactly what constitutes “discarded items”.
There is also a demand for signs in both Chinese and English in the lavatories and better disabled access.
The new requirements are not compulsory and only aim to improve the Chinese capital’s notoriously unpleasant public lavatories, Xie Guomin, head of the sanitation management division of BMCCAE told the Beijing Times.
