I am planning to book a flight from Dubai to Manila vice versa, but I've noticed there is a stopover of more than 10 hours in Beijing from Dubai to Manila and 9 hours stopover from Manila to Dubai. I am thinking if I can go out of the airport and make a short tour of the city. Is that possible? Do I need to secure a visa? What if I want to make a short tour on both occasions (ie, Dubai-Manila and Manila-Dubai), do I need to secure separate visa for different dates? And how much will the visa costs?
