     As computers become all the more popular in China, Chinese people are increasingly relying

on computer keyboards to input Chinese characters. But if they use the computer too much, they

may end up forgetting the exact strokes(笔画) of each Chinese character when writing on paper.

Experts suggest people, especially students, write by hand more.

     Do you write by hand more or type more? In Beijing, students start using a computer as early

as in primary school. And computer dependence is more wide-spread among university students.

Almost all their assignments and essays are typed on a computer.

    All the students interviewed say they usually use a computer.

    It's faster and easier to correct if using a computer. And that's why computers are being applied

more and more often to modern education. But when people are taking stock in computers increasingly,

problems appear.

    "When I'm writing with a pen, I find I often can't remember how to write a character, though I feel

I'm familiar with it."

     "I'm not in the mood to write when faced with a pen and paper."

     Many students don't feel this is something to worry about. Now that it's more convenient and

efficient to write on a computer, why bother to handwrite?

     Many educators think differently. Shi Liwei, the headmaster of a famous primary school in the

capital said, "Chinese characters enjoy both practical and aesthetic(审美的) value. But those

characters typed with computer keyboards only maintain their practical value. All the artistic beauty

of the characters is lost. And handwriting contains the writer's emotion. Through one's handwriting,

people can get to know one's thinking and personality. Beautiful writing will give people a better first

impression of them."

     To encourage students to handwrite more, many primary schools in Beijing have made writing

classes compulsory and in universities, some professors are asking students to turn in their homework

and essays written by hand.
