I am now in Hanoi and flying with China Eastern Airlines on the 29th of January to Beijing.

There I would fly back to the Netherlands as the 31st of January and want to use the 72hr transit free transit. However, my flight from Hanoi to Beijing has a transfer in Kunming. Am I able to transfer here because I do not have a valid Chinese visa? And am I able to apply for a 72hr free transit because I come from Kunming? Thank for your help in advance! Maikel
