When Tsai was a child, comic books were all the rage and he would go to comic book stores after school. After reading many of them, he started to imitate them. He drew constantly, and he would staple his creations into books and give them to his classmates to read.
蔡志忠成長的年代，正是葉宏甲《諸葛四郎大戰魔鬼黨》、陳海宏《小俠龍捲風》等漫畫書風靡的時候，課餘時間他就去漫畫書店，看多了也有樣學樣，每天不停地畫，還會自己訂成一冊，供同學瀏覽。
