Xu Youran, a young and transparent member of the provincial team, accidentally entered the first national team of Chinese women's table tennis. Rookies are like leaping through the dragon gate, but they are surprised at every step - rigorous team training, stressful tryouts, infighting within the team, love and friendship in adolescence, the tug-of-war between huge dreams and self-doubt... There are also humorous companions, arrogant opponents, and chaotic but warm family support. As the seasons change, how does she use a table tennis racket to break through the waves of life and finally stand on top of the world? The book is full of ups and downs, depicting personal growth, team bonds, friendship, competition, dreams and tears in a humorous and passionate youthful style.
