Want to know the name of a song

Singer: Wang Ziwei

Lyrics:

Why did the sky seem to cry/why did it fade/why did my heart wither and grow into a desert/flooded thousands of rivers/what fell and passed/blurred vision could not tell what color/you promised not to leave me/but suddenly left without saying anything//leaving me alone to watch the dream fade/only the sky accompanied me over and over again/it turned out that we were equally fragile/you left me alone to watch the dream fade/only the sky.
