    My name is Jerry Zhang, and I am a father of two young daughters -- one is about four years old and the other is only about one.我来自中国，现在住在美国。

    One day, my older daughter, Madison, told me she didn't want to be Chinese. Those days she was quite interested in the book characters (角色) Madeline and Eloise. She asked me all the time why she was Chinese and they weren't, and how she could have yellow or red hair like them.

    This made me look for books with Asian (亚洲的) characters for Madison to read. However, I only found a few, and they were heavily cultural (文化的) and Madison didn't connect herself with any of the characters in them. And she wash' t interested in them at all Then she told me again that she didn't want to be Chinese, and it made me sad.

    In most of the books for children in the US, the characters look like Americans. There are over 17 million Asians and Asians and Americans in this count, but few of them have Asian faces. I think it's important for Asian children to see themselves in books as interesting and clever kids.

    So I created (创作) a book for Madison. Pepper Zhang in the book is an Asian girl. Her imagination (想象) takes her on a trip to creativity and art I want my children to know that being Chinese or being Asian is a great thing too.
