Dear host family Mom and Dad,

Thank you very much for your kindness. I’m Yujia Liao, 14 years old, writing to you from China. My English name is Eugene. I am so excited about the chance to live with you during the next school year.

At present, I live with my parents in Yiyang, a beautiful small town in China’s Hunan Province. We are all nice people. I am the only child in my family. My dad is the general manager of a bank in my hometown. He tells me valuable knowledges and gives me instructions, teaching me how to become a good person. My mom works for China Mobile Communication Company. She always takes good care of me. To make sure I can eat well at school, she would even deliver meals to me during her lunch break. I love them both.

I like reading. One of my favourite books is Harry Potter. When I feel bored, I like listening to light music. I also like riding bike with friends.

I love animals, especially dogs. But I have never got a pet before because my parents thought there is not enough time for me to take care of them. If you have got one, I will be happy to help you to take care of it.
I am outgoing and friendly, thus making friends easily. Please believe I will get along well with you and your family.
When I got my first computer and smart phone, I was interested in how those cool stuff actually worked. I want to stay in America and find a good university to study computer science. My dream is to become a computer engineer after finishing university study.

As far as I know, American students are independent in learning. They can learn by themselves under no supervisions and instructions. Also teachers don’t need to keep an eye on them. I like this kind of school. And that’s why I’m coming to America for high school.
Thanks again from my Chinese parents and me for your kindness.
Hope to see you soon at Ohio.

Love, Eugene
