Hard to find toilet in Hong Kong

Problem: 64% (up), 36% (down)

Solution: 73% (up), 27% (down)

Will pay? 21% (yes), 89% (no)


I want to build a mobility toilet across Hong Kong including inside a building like shopping mall or museum. The mobility toilet will go around with siren when it is available so that people will aware of it. We can create an apps to search where is the mobility toilet nearest to us.
