Vietnam-Cambodia-If I return to Vietnam and fly back to China, can I leave Vietnam with a Cambodian visa? Do I need to sign again when I enter Vietnam for the second time

You should get a visa to Vietnam first (multiple entry and exit). Generally, it costs 350-450 yuan for one month and 900 yuan for three months (the price can be negotiated, and the fees charged by consulates will vary). You can go to the Vietnamese consulate yourself and get it in 3-5 days. You need to increase a little money quickly. When filling out the application form, you must emphasize that it is multiple entry and exit, or you will have to spend hundreds of dollars to re-sign it when you go to Cambodia and return to Vietnam, which will be a loss. There are consulates in Beijing, Guangzhou, Guangxi, Shanghai and Yunnan. ) Let the travel agency worry about it.

You also need to apply for a health certificate and vaccination certificate, valid for 1 year, 180 yuan. If you don't want to do it, put a 30 yuan RMB in your passport and give it to the quarantine officer when you enter the country. You'd better have one, because you're going to Cambodia.

After arriving in Vietnam, you can apply for a Cambodian visa in Hanoi (or Ho Chi Minh), and the fee does not exceed 50 dollars. Or it is more convenient to apply for a Cambodian visa directly in China.

From South Vietnam to Cambodia, South Vietnam has the strongest flavor and the most beautiful scenery.
