Visa on arrival at Zhuhai, available?

In fact, you can directly apply for a L type one in Macau and then go to Zhuhai. In this way, you won't be worried about refusal.

Thank you, but how fast can such a L type one in Macau be arranged? Because I'm actually staying in HK and will go to Macau for just a day trip (without overnight staying).

I am not sure how long it takes. I give you this suggestion because I am afraid that you might be refused when applying for the VOA. Actually, you can apply for a L type one easily in HK. It's very fast. You may try to apply for the VOA at Zhuhai Border. If you are refused, then you need to apply for a L type one either in Macau or HK.
