I have real pen pals. She and I met in our senior year of high school. In 1998, we corresponded until I was in my fourth year of college. She studied in a junior college in Beijing and I studied in the south for my undergraduate degree. She is a girl with a lot of personality, and of course, as described in many stories, she is a beautiful girl. We have approximately more than 300 letters of correspondence. Her handwriting is very graceful, but her personality is carefree. She sent me coffee, paper cranes, paintings she drew, and even medicine in my letters. She and I are just pen pals, but we have different feelings. She and I only met once. She came to my city just to see me. Later, she went to the UK to study, and we lost contact because she lost her contact information. In the article I wrote, I typed the original letter she wrote without any processing. In modern society, with advanced communications, we have long put down our pens and tapped our keyboards. However, the feeling of writing a paper letter and reading a paper book is really different.
