Actually, the feelings of the composers on the scene also mirror those of the viewers.
After the program ended.
There are many discussions online about the final scene of the live broadcast such as:
"Father Yang is awesome, he really didn't have any stock-piled songs!"
"The older the ginger, the spicier. Father Yang actually drew with Fish Papa without any stock-piled songs!"
"It's not that mysterious, Father Yang himself said that he was just lucky to get inspired. Sometimes, inspiration comes inexplicably."
Not all classic songs are painstakingly written over countless years.
"But Fish Papa is totally fine too, he directly admitted that he used his stock-piled songs."
"He could have boasted saying that he wrote the song on the spot. We wouldn't have known."
