It’s possible to get the 3 days visa Zhuhai via the HMZB ? I wanna try the new bridge

The answer is, definitely yes! You will take a bus departing from Hong Kong for Zhuhai port, i.e. the facility on the artificial island that is located in front of both Macau and Zhuhai. There you will encounter a place, in reality a counter where you will apply for Zhuhai 3 day VOA. Last reports indicate that the authorities at that particular place prefer credit card payment over cash, but the advice is still taht you take a cash just in case. I mean mainland China cash - CNY because you can easily obtain it in Hong Kong at many money changer offices. After you have received your VOA you will just proceed by bus in the center of Zhuhai.
