What were the 10 most trendy words used by mainland youth last year? Young people from all over China, including Hong Kong, are invited to vote on their choice. A list, which contains more than 30 entries, is available on www.ynet.com until March 31. Co-organised by China Youth Studies and Beijing Youth Daily, and supported by youth-oriented newspapers, magazines and Web sites, the activity could become an annual event to document the ever-changing youth culture. The list covers a wide range of topics, including serious issues. Among the entries are '9-11', 'bin Laden', 'WTO', 'anti-terrorism' and 'Olympics'. Others reflect youth culture - 'cool', 'mei-mei' (pretty girls), 'MP3' and 'flash'. Then there are words such as 'knowledgist' that have been invented in response to new-economy phenomena. You can also type in your own suggestions. Each week, 20 lucky voters will be given prizes for their participation.
