I just arrived in Beijing, making a detour coming back from MAX Japan to spend 3 days in China (in Beijing and Hangzhou, and then leaving via Shanghai) for Flex and AIR related meetings and presentations. This is my first time in China (I have visited Hong Kong and Taiwan previously, but never Mainland China), and I plan to spend some time tomorrow seeing the sights.
Passengers arriving in to China must complete a "Health Quarantine Declaration Form" identifying any ailments and diseases they may have by checking the appropriate boxes. For some reason I found the range of diseases listed very amusing. The list started with snivels, cold, and vomiting, and progressed to venereal disease, leprosy, HIV/AIDS, open pulmonary tuberculosis, and ended with psychosis. (I just can't help but wonder how many people check that last box).
