Ah Shai originally had a small upward-turned nose bridge, but one day Ah Shai got into the habit of sleeping in class, and the bridge of his nose became very hidden (some say it was suppressed) (Volume 5 instructions). Ah Shai's best friend is Xiao Chong. Ah Shai's deskmate is a girl with a big face. Ah Shai has a crush on the class beauty of the class next door. He is often criticized by his class teacher Dangdang and later his class teacher Jin Chengwu (appears in the ninth volume), and is always beaten by his parents. The comic "Ah Shai on Line" describes the life stories between junior high school student Ah Shai and his classmates, teachers and parents. Ah Shai in the story is flamboyant and frivolous, lacking stability, prone to random thoughts, unrealistic, whimsical, and always hoping for something to fall into the sky. Tasty, lazy, immature, and very lazy make the story hilarious and very popular among students.

Ah Shai loves to eat stinky tofu, and his trademark is a mushroom head! Later it was released on DVD. Registered trademark in 2008.
