Hey Guys, thanks for the feedback. 
I was thinking of something around this. Considering that I do not speak the language, I am often dependent on taxi, and some prices sometimes inflate just because I am a foreigner, for now 15k should be ok.
and what about “fapiao”. Should I demand it? Some people I met here from other areas said it is a must. Others like me didn#t even know that this exists until recently, after arriving in China.
