Hi-- I am traveling to Beijing in May, and plan to take a train to Shanghai and continue by train to Hanoi and Ho Chi Minh City, flying from Ho Chi Minh to Bangkok, Taiwan, and back to Tokyo (where I am living). Will my plane tickets from those cities be OK for getting a Chinese visa or do I need to show actual exit tickets from China? Can I book my train ticket out of China in advance and use that for the Chinese visa?

Thanks, Jamie
