In the program, Song revealed that his real name was not Song, but Song was just a nickname. Song's grandfather was named Song Shuli. Song Xuanya is a "tree" in his hometown. For the sake of genealogy, he was named Song Shuli. Song Xuan Ya was brought up by his grandfather in his hometown in Shandong when he was a child, and then came to Guangdong with his parents.

Song's nickname:

1, Village, mainly because Song participated in a variety show in the past, and then the variety show was called "Pig Variety", so fans wanted to give him a more grounded nickname and be closer to this variety show, so Song was called "Village".

Ya ya, because the word "ya" in his name is homophonic with "ya", so "ya ya" became "ya ya" under the shout of everyone. In addition, this nickname has a deep meaning in the eyes of fans, that is, everyone hopes that Song can grow from a small bud to a towering tree like a big tree.
