    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 1: Do your homework

    Read everything you call before going. Really study the maps. Know the pavilions. Arrive at the entrance

nearest Io 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 man

hack 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 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 days 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 all 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 whatever you do, don't miss it!
