　　Expo 2010 is held in Shanghai from May 1 to October 31. People all over
the world are looking forward to it. Here are several golden rules on how to best
plan your trip.
　　Rule l : Do your homework
　　Read everything you can before going. Really study the maps. Know the
pavilions. Arrive at the entrance nearest to the things you want to see. Have a
plan. It will make a big difference.
　　Rule 2:Allow plenty of time
　　Expo 2010 is the largest attraction event in the history of the world. It will
take many days to see it. Plan to spend from five to eight days or more seeing it.
　　Rule 3 : Pace yourself
　　Expo is enormous. The distances are punishing. It is better to spend a day
seeing a single area than to run back and forth all over the site. Remember to
wear the most comfortable shoes. Never mind what they look like.
　　Rule 4:Get going in May
　　At many Expos the crowds are smaller in May and in early June than at any
other time. And beware the last two weeks. During every Expo, people delay
their visits and then in early October they suddenly realize, "Expo will close
soon! I haven't seen it!" As a result, the last several weeks usually have the most
crowded of the entire Expo.
　　Rule 5: Find out what everyone else is doing  and do the opposite.
　　If you don't like large crowds and long lines do the opposite. Here is an
example: Most people go on Saturdays or on holidays. So avoid Saturdays and
holidays. Go on weekdays when most people are at work.
　　Rule 6 : Turn up
　　Expo 2010 is the largest celebration in China's history an amazing
once-in-a-lifetime event. When it is gone and it will never be seen again. So
