moondog, I think your standard drill should start with checking that the meter has been reset

otherwise, it is good advice.
In any event, given how cheap cabs are in China anyway, getting ripped off is usually a matter of a buck or two, nothing worth stressing about.
Also, note that there are different cab prices based on the size of the cab. So, the same ride on the return will not necessarily cost the same as the fare going. The prices are clearly marked by the passenger doors though.
