     Several days ago, while I was logging onto QQ, my cousin's QQ head popped out online. We hadn't

seen each other for a few months, so I decided to start a conversation with her. My cousin is studying in

a college of our city. Her hobby is surfing the Internet. Every time I am on the computer, she is always

online, listening to music or decorating her "personal space". I like visiting her space. It's creative and

modern and worth a visit. I can't imagine my designing such a colorful web page.

     When I read the sentences she sent to me, I noticed that the Chinese characters had been changed,

but I could still guess their meanings. I took a strong interest in this type of new characters. Further

observation made me realize that they added some common Chinese radicals (部首) to the original

characters, making them more vivid, a little like Japanese. My cousin said this gives new life to the

Chinese language and culture.

     It is true that the Internet has reinvented our language, but I still can't accept this new cultural change.

Some Chinese characters have meanings in the shapes; one shouldn't superficially change them by adding

an additional radical. So I persuaded my cousin to change her new idea and use standard characters to

communicate. And she willingly accepted my advice.
