Is it easy to get a visa at the Chinese embassy in Burma

Whether it is easy or not is hard to tell, because the embassy has final right to decide whether to issue or not. Personally speaking, you can have a try there. You need to prepare your valid passport, application form with recent taken photo, your visa for Burma, local Forigner Registration Certificate, the latest entering Burma proof, round trip tickets to China and hotel booking in China for application. Usually, it takes around 4 working days to get it.
