Looking for the background of Sun Nan's song "Salvation"

There is really no creative background to save this song. The lyrics of a simple emotional song are obvious. In the classification of songs, it also belongs to the category of sad love songs. There is really no creative background, and this song is included in Sun Nan's "Destiny's Sky" album, which is not specially written for the disaster area. The landlord can Baidu, there is really no background, hehe.
