In Class 5 of Qiushi Primary School, there is a special trio. They are good friends with Mi Xiaoquan and Tietou.The three of them are inseparable, whether they are studying or playing, they are together and become a unique scenery in the class.

The central figure in this trio has extremely large teeth, hence the name “Big Teeth”.Not only does he have big teeth, but he also has a lively and cheerful personality, always with a sunny smile.He is also famous for his venomous tongue, which often makes people laugh or cry.His father is the chairman of Daya Group, which adds a bit of mystery and brilliance to him in the eyes of his classmates.

“Daya”'s favorite person is his deskmate Pan Meiduo.Pan Meiduo is a quiet girl with excellent academic performance. She always brings a lot of help to “Daya” in her studies.“Daya” often used his liveliness and cheerfulness to infect Pan Meiduo, and the relationship between the two became increasingly close.

However, not everyone in Class 5 of Qiushi Primary School likes “Daya”.Once upon a time, he and He Wei were mortal enemies.He Wei is an introverted boy who always likes to sit alone in the corner silently.And “Daya” always likes to show off his various skills in front of He Wei, which makes He Wei very dissatisfied.As a result, the conflict between the two became deeper and deeper.

However, as time went by, the antagonistic relationship between the two gradually resolved.They began to understand and respect each other, and even became good friends.This surprised the whole class and made them understand more about the value of friendship.
