on the way to shangri-la we take a loo break at a heavy vehicle check-in stop. the complex is vast and the loos are right in the back and quite ammoniacal from before you get to them.
i approach the bank of doors and push one open to find a woman crouched over the loo and back away in embarrassment. she is however most kind and tells me, go down this way. you'll find plenty of loos without doors there!
i do love visiting china but i confess i am not intrepid at all. also, i need doors.
