Dear David,
I'm glad to receive your letter. Here is my advice for your trip to China.
First, Beijing is the most worth - visiting city. It's the capital of China and has a long history. You can visit many famous places like the Great Wall, the Forbidden City and the Summer Palace. These places show the profound Chinese culture.
Second, the high - speed railway is the best way to travel between cities in China. It's fast, comfortable and convenient. You can enjoy the beautiful scenery along the way.
Finally, you can buy some Chinese knots or silk scarves as gifts for your friends. They are traditional Chinese handicrafts with beautiful meanings.
I hope you have a wonderful trip in China.
Best wishes!
Yours,
Li Ming
