Lining up to use woman's lavatories is expected to become history in Shanghai, as the local government will build enough toilets to meet the demand. 
 
The situation is much better for men.

There are roughly as many public toilet seats for women as there are for men: the planners obviously forgot a basic anatomical difference between the sexes!
The municipal environmental sanitation department estimates that there should be over 30 percent more for women than for men.

The planning of public lavatories will be one of the topics in the international public toilets forum to be held next year in Shanghai
