China Public Toilet

This morning read an email about China toilet. Now only I remembered I had bad experience while in China. Their public toilet really dirty and narrow. I'm so scared to go those public toilet until I hold myself for long to search for nicer restaurant or hotel's toilet. There is one time I have to go to the underground plaza toilet, and before enter the toilet there is a sign mentioned those toilets only for ladies. I thought is ok but then when entered inside really dirty and dark. Well because emergency so I have to go in. Who knows the door can't lock! Not only this frighten me, the most scary thing is I can see people passing thru in front of the door no matter gals or guys! then I only know that alure is the route to carpark leh! It is so unsecure.
