Along with the Japanese 3D animation film "Stand by me Doraemon" premiering in Chinese cinemas, the Chinese version of its theme song "Promise from Sunflower" has become a hit on a Chinese website.

The song performed by China's young singer-composer Jin Guisheng has reached a listening rate of 5 million on a single platform in China within a week.

As the original manga which the film is based has been enjoyed by generations of young people, the song is said to remind many of their childhood.

The film has been a huge box office hit in Japan earning more than $70 million since its release last August.
