The lyrics "You are the heaviest in my heart, and my tears rush to the sky" means that in one person's heart, another person occupies an extremely important position and is irreplaceable. However, for some reason, this person may be about to leave or have left, resulting in uncontrollable pain and tears that can only be washed into the sky.
This lyric comes from the song Farewell My Concubine, which is a popular China song sung by Tu Honggang. Chen Tao wrote the lyrics and Feng Xiaoquan composed the music. 1996 was released as a single EP, and then included in the album "China Kung Fu" released by Tu Honggang 1997 in February.
