Just to be smart! For example, when you take a taxi, please show the driver your destination on the map clearly. Or, get the probable fare in advance. Please take it easy that the drivers in HK are honest.

Please take some HK$ at small bill. Most of the places in HK accept credit card. Actually, it is not easily to bargain with the wholesaler at the Ladies Market. But try to cut half down if you indeed would like to purchase something.
