"It rained heavily and the streets were flooded..." This clear and beautiful girl's voice fascinated countless audiences at the opening ceremony of the Asian Games. Many people are curious, who is this little girl who "only hears her voice but does not see her body"? She is Chen Sitong, a 9-year-old girl from Guangzhou. She is still in the fourth grade of elementary school and is a member of the Little Skylark Chorus of the Children's Palace in Yuexiu District, Guangzhou. "Heavy Rain" is the only Guangdong nursery rhyme that Li Haiying, the music director of the opening and closing ceremonies of the Guangzhou Asian Games, praised at the opening ceremony. As a singer, Chen Sitong is both lucky and talented.

Sitong is still in the fourth grade of elementary school and is a member of the Little Skylark Chorus of the Children's Palace in Yuexiu District, Guangzhou. In July 2010, Li Haiying, the music director of the opening and closing ceremonies, asked the Yuexiu District Children's Palace and others to recommend dozens of girls around 10 years old who looked "as cute as Lin Miaoke", saying that there would be a chorus or solo session at the prelude to the opening ceremony. It is a nursery rhyme from Guangdong.

After rounds of screening, only Chen Sitong and another girl were left for the final audition. Just the night before entering the recording studio, Sitong officially received Li Haiying's final score of "Heavy Rain".

My classmate is thinking of Bel Canto, but according to Li Haiying's request, although the pitch is raised, the nursery rhymes must highlight the natural children's voice. Therefore, the professional singing method of Bel Canto cannot be used, but the original voice must be used. The highest part of the song alone was sung more than twenty times that night. "The other girl really couldn't sing anymore at the end." Sitong got the opportunity to record and sing the song "It's Raining Heavy".

“Sitong has a good temperament and is suitable for taking photos.” Teacher Deng of the Little Skylark Chorus of Yuexiu District Children’s Palace recalled, “At that time, according to the requirements, the organizing committee hoped that the performers would be younger and more beautiful, so we Sitong was recommended and selected.”
