Dear Peter,
亲爱的彼得，
I have gladly received your letter telling me that you’re interested in traditional Chinese musical instruments. Now, I’d like to tell you something about the Chinese Zither, one of the most ancient Chinese musical instruments with a long history of over 2500 years.
我很高兴收到你的来信，告诉我你对中国传统乐器感兴趣。现在，我想给大家介绍一下中国古筝，它是中国最古老的乐器之一，有2500多年的历史。
The Chinese Zither is a plucked instrument and is played with both hands. In the early times it had 5 stringsand has developed into 21 to 25 strings up to now.
古筝是一种弹拨乐器，用双手弹奏。早期有5根弦，到现在已经发展成21到25根弦。
The Chinese Zither has a wide range and sonorous sound. As its playing appears and sounds like playing the piano,the Chinese Zither is sometimes called "the Chinese piano".
古筝音域宽广，声音洪亮。由于古筝的演奏听起来像弹钢琴，所以它有时被称为"中国钢琴"。
Enclosed with the letter is a CD of masterpieces of the Chinese Zither. I hope you’ll enjoy it.
随信附上一张古筝名曲光盘。我希望你会喜欢。
Best wishes!
最美好的祝福！
Yours,
你的，
Li Hua
李华
