The World Carnival is set to start its second funfair in Beijing at the end of the month. While young people can hardly wait to rush to the huge mobile amusement park, people living in the neighborhood where the carnival locates are worrying about the possible environmental damage. Last summer the World Carnival left Beijing with a huge scar on the grassland of the International Sculpture Park. To help the settlement of the mobile amusement park, about 55,000 square meters of greenery was removed last year, including nearly 200 big trees. This year however, the World Carnival has been more careful in settling people’s concerns. An environmental evaluation has been done to the whole project and the report approved. William Stevens, Chairman of World Carnival Ltd. further explains. And if you’re keen to go to this year’s carnival and you’ve never been to one before, the following are some tips our entertainment editors have summarized.
    Do not wear skirts ,or clothes made of filmy material;
    Do not hang down your hair loosely;
    Take off your spectacles before enjoying thrill rides;
    Do not wear slippers;
    Leave games for the end of your day’s enjoyment to avoid the burden of carrying around big prizes;
    Do not eat too much or leave your stomach empty before enjoying yourself;
    And finally, do not overindulge in the games or rides.
