AAAGH! The Generation 90s is coming!

Wearing earphones, using complex Net language and constantly text messaging friends, the Gen-90s following the Gen-80s begin to make their world debut (初次登台).

Each generation or age group has its own symbols and lifestyle. Read on and judge for yourselves if you fit the Gen-90s group.                

Earphones

These little devices seem to grow on the heads of the Gen-90s. They might lead to MP3, MP4 or MP101 players, giving these young people a plugged-in, cool and perhaps self-addicted look, of course, life is not always music to the ears.      

Martian language

They have created their own code-like online language. It’s a mixture of English, Japanese and Chinese that perhaps only Martians can understand. This is an imaginative generation, though they need to be careful to keep it out of their term papers.                 

Self-Portrait

Saying “cheese” to their own digital cameras is usual for this generation. A little bit of narcissism (自恋) never hurts anyone. It helps them reflect a little on their own lives．But be aware of the risks of posting private photos online.

Text-messaging
