Wang Xin, formerly known as Wang Ruoxue, was born in a poor family in Wuhan, Hubei. Later, when she joined the Tsinghua University diving team, Yu Fen, the coach of diving queen Fu Mingxia, thought that "if" and "weak" were homophonic, so she became Wang Xin now. Three gold-lettered Xin pinned their hopes on the little girl, hoping that she could win more gold medals. This hope is now being realized. But Wang Xin used to be afraid of water. When he was a child, he went to the swimming pool with his parents. He didn't dare to go down at all. He just kept the steps and played by the pool.

Like many divers, Wang Xin started out as a gymnast. Wang Xin practiced gymnastics at the age of 10. In 2000, those who practiced gymnastics for more than two years began to practice diving under the guidance of their first coach, Wang. Because of his previous gymnastics training, Wang Xin has made rapid progress. In 2003, Wang Xin was transferred to Tianjin diving team and began professional training. In 2006, she achieved triple jump and entered the dream team that divers in China dreamed of.

Wang Xin's training in the national team has been greatly influenced by international high-level athletes, and she has rapidly grown from a small player to the main force of the national team. In 2007, Wang Xin, who was only 15 years old, began to appear frequently in international competitions. The platform duo composed of her and Chen suddenly became a hurricane sweeping the diving world. That year, they searched all the international women's 10 meter platform champions. In addition, Wang Xin also participated in the single platform diving competition and sometimes won a gold medal.

The same action, turning hundreds of somersaults every day, is repeated countless times. In this process, Wang Xin grows bit by bit. In this process of growth, Wang Xin slowly goes higher and higher. Finally, the smiling girl stands on the Olympic gold medal podium, making the world remember her smile. In the 20 10 national diving championship, the women's 10 platform did not perform well and only ranked 10.
