Having Fun “Growing” and “Stealing”

Recently, an Internet game has become a new fashion among young office workers and students. People can “farm” on a piece of  “land” and “grow”, “sell” or even “steal” “vegetables”, “flowers” and “fruits” on the internet.

They can earn some e-money and buy more “seeds”, “pets” and even “houses”.

Joyce interviewed some young people. Here are their opinions.

Harold:I don't quite understand why they are so mad about the childish game, maybe they are just not confident enough to face the real world.

Allan:I enjoy putting some “bugs” (臭虫) in my friends’ gardens and we’ve become closer because of the game. Having fun together is the most exciting thing about it.

Laura:You know, people in the city wish for the life in the countryside. It relaxes my work pressure; besides, it gives me the exciting experience of being a “thief”.
