Public bathroom in Yunnan

The public toilet in Yunnan is not for free ,the standard price is half yuan which is 5 jiao ,most of the toilet keeper dont speak English , so they use their fingers to show how much they charge .sometimes my clients come back from the bathroom complaining they payed 5 dollars instead of 5 jiao out of misunderstand the toilet culture , i guess if this happen to you next time in china is the lucky day for the keeper !
