I have just been going through an English translation of “Legal Guidelines for Foreigners Entering, Exiting and Staying in China during
the Olympics“. Anyone going to China for the Olympics, should at least have a glance through the document.

The good news is you can bring your dog or cat to the Olympics, although they will still have to go through the quarantine process and only one pet per person please.

People renting an apartment or staying with a friend or Chinese family will need to register with the police within 24-hours of their arrival. The landlord/agent should be able to help with this.

China does not recognize International Driving Permits. You will need to go through the formality of getting a Chinese driver’s license if you want to drive in China. The authorities take this issue fairly seriously, if you get caught you could spend the Olympics in a Chinese jail. Getting a local driver is cheap and it can save a lot of hassle.

Point 35 is interesting:

35. What are China’s main public places of entertainment?

Public places of entertainment, including include nightclubs, dance clubs, erotic dance clubs, karaoke bars,
discos, arcades etc, are open to the public as places of business for patrons to enjoy themselves.

Erotic dance clubs? Where are these places? You would think the could have provided a listing of such clubs.

And finally on reselling of Olympic tickets:

46. Can Olympics admission tickets be freely resold?

The tickets can be lawfully resold. The resale of admission tickets to the opening and closing ceremonies of the Olympic Games (including the Paralympics), must be authorized by the Beijing Olympic Organizing Committee and must go through the formalities in accordance with policies on admission ticket resale as stipulated by the Beijing Olympic Organizing Committee. The specific procedure for reselling tickets can be found on the official ticketing website.

The opening and closing ceremony tickets contain the owners details including a picture and passport details. So, you will need to get the tickets properly transferred if are looking to buy or sell tickets. For other events, as long as it doesn’t involve a Chinese team, it should be fairly easy to find tickets for sale.
