The song "Heart Sutra" was sung by Faye Wong as early as May 2009 during the rehearsal of the "Famen" large-scale party "The Completion of the Namaste Relic Pagoda and the Ceremony of the Buddha's Finger Relic Enshrinement" at Famen Temple in Shaanxi Province, and Not created specifically for the film. The lyrics follow the original text of the Buddhist classic "Heart Sutra", and the style of the music is also very distinctive Buddhist music. Ethereal and beautiful, it is like a clear stream of sweet rain that cleanses people's souls. It lifts the souls of the 240,000 victims of the Tangshan earthquake 32 years ago, and gently heals the long-suffering pain in the hearts of the survivors. After listening to it, I couldn't help but feel calm and thoughtful. Towards the end of the song, the singer mellows it, blending it with a slightly hymn-like singing style, making it even more grand and inclusive. The singer's appearance is also like that of a saint - wearing a white dress, with a calm expression, she sings eloquently, and the heart sutra is deeply rooted in people's hearts.
