One and Only is a 2023 Chinese youthful inspirational comedy film directed and co-written by Dong Chengpeng.

Facing with the constant pull of family obligations and dreams, Chen Shuo is firm in his original aspirations.

While working hard to support his family, he is also constantly moving towards pursuing his dream of being a professional breakdancer.

He runs back and forth between life and passion, trying to balance between faith and reality, and writing a hymn to his youth with his own determined will.

The film also tells the audience a story of inter-generational inheritance: when Ding Lei, a veteran street dancer, meets Chen Shuo, a young street dancer, Ding Lei's words "keep working hard and you will succeed" rekindle the youngster's faith; and Chen Shuo's perseverance and hard work have also restored the initial aspiration of this disillusioned street dance veteran.
