Song's trump card versus peacock. Which issue flies southeast?

Peacock Flying Southeast in Song Dynasty's Ace to Ace is the seventh issue of the eighth season.

According to Douban, in the eighth season of "Ace to Ace", Song Xuanya sang a famous song "Peacock Flying Southeast", which took place in the seventh period of the program. I saw the fierce and pleasant competition and debate between Song and Jin Jing.
