Chinese women have been occupying men's toilets. These brave cistern sisters are raising awareness of a terrible lavatorial gender imbalance in China: for every ONE female public loo, there are 2.3 gents' loos. The China Desk lifts the lid on this issue and also wonders: are the Chinese now more prone to protest? The sit-ins - or shall we say squat-ins? - of 'man cans' come after the siege of Wukan, the village which rose in protest against local officials. Are these expressions of a more combative national mood?
