Creative background:

The ending song "Shuang" of Aska Yang's TV series "to the sky kingdom" was moved by powerful singers Diamond and Aska Yang. In the form of duet between men and women, it tries to express Bai Qian's voice from the angle of gentle female voice. From longing to heartbreak, I don't regret this magical love. Diamond's musical interpretation and melody evolution have hardly changed, while Aska Yang's male interpretation has left the impression that the female voice is too soft and ethereal.

It is surrounded by tenderness, which makes people feel safe. Aska Yang's mellow and delicate voice echoes Diamond from a distance, forming a tacit musical atmosphere, allowing the audience to reach the great dream of "Three Stones and Three Peach Blossoms" in advance in the coolness.
