I am a singer. Why did Sun Nan suddenly quit in the third season?

Sun Nan withdrew from the competition in the final, which was not noble, but ugly and even unbearable. It is disrespectful to everyone, including the audience, other singers and even Hunan Satellite TV! Sun Nan used to be the mainstream of music in China, but it is this mainstream that has long hindered the development of pop music in China. The ending song of domestic TV series, sung at night, with constipated voice and face piled together, is a song in the music world. This is a joke for 20 years! Look at the world pop music scene. Only China has such a freak. This is a disease of China pop music, and it is not an incurable disease. It's a pity that the mainstream media has been embellishing it and pushing this most disgusting thing to the public: eat, it's delicious! As everyone knows, what they admire is obviously a pile of shit.
