I live in Europe. I will be flying to Shanghai and travelling south to Nanning for 1 month. Then I will leave to Vietnam by train. My flight back to Europe from Asia is 4 months later, so I don't have any ticket out of China - I'm flying back from Bangkok.
As far as I know I cannot get the visa without it. One solution I see would be to buy a plane ticket from Nanning to Hanoi, and specifying this in the visa application.
The problem is that it's very expensive. How can I be sure that after spending so much money I will get the visa in the end?
Is there an easier solution to this?
