Self-introduction: My name is Adam Johnson. I am a senior at Cupertino High School in California. I have been very interested in the 26 English letters of ABC since I was a child, and I have been using these simple 26 letters for art creation. When I was 10 years old, I started my own channel on YouTube, publishing Animation (animation game), Reaction (reaction ability), Gaming (guide game), etc., attracting tens of thousands of viewers. I love computers, and I am a member of the San Francisco Youth Computer Pioneer Group. Weekends are happy hour for our members to learn from each other. I like to watch many sports programs, also find time to play basketball, table tennis, and often participate in sports activities organized by our church on Saturdays.
