Xiao Sangsang was originally very happy today because Mu Caisang had promised to take her to the amusement park to play. There were many kids in the amusement park, and she hoped to make some friends. However, Mu Caisang was called away by Wen Zhongyuan to discuss some matters, so Xiao Sangsang was left at home and forbidden to go out until her return.
Xiao Sangsang was very sad, and after Mu Caisang left, she couldn't hold back any longer. She stopped listening to Mu Caisang's instructions, used a small stool to reach the door handle, opened the door, and ran out to play by herself.
She wanted to go where there were other children, to make friends, and to not be alone anymore. She remembered there was a park near the neighborhood where she saw many kids when Mu Caisang took her there, so she went to that park, guided by her memory.
