Rui Zai is a transfer student from Mengda Kindergarten. Some of his classmates are very friendly to him, while others are weird.
Faced with unfriendly faces and voices, Rui Zai didn't want to go to kindergarten.
No matter how his parents asked him the reason, he would not tell him. Until one day, in his dream, he met a cute little dumpling. The little dumpling taught him a great skill, that is - learning to say "no".
Purpose: Learn to say no and refuse bullying
