Ma Xiaoxiao is a considerate sister next door, sometimes calm and sometimes headstrong. She is a famous genius in Mayang Street. She is bent on being admitted to Peking University, not afraid of difficulties, working hard and persisting.

In front of the little friends who grew up together, she became a reliable "Mayang Street Elder Sister" and always protected her most important friend. In front of parents and neighbors, she is a sensible and worry-free daughter. Only in front of the person she likes will she show some anxiety.

At the end of the TV series, I was with the male No.2 Yi Dongdong, and I didn't choose childhood friends. The male dominated Europe. The ending of this TV series is a bit unexpected, but it is also an unexpected ending, which also brings different feelings to the audience.

Ma Xiaoxiao in the play is a lively and cheerful girl who loves to draw swords and help others. People around her like her very much, and she influences everyone around her with her kindness. I have always liked Ou since I was a child, but Ou suddenly gave up on himself and was forced to drop out of the police academy and mix with socially unhealthy young people.
