The word "public opinion" appeared earlier in China, and was mentioned in Guoyu of the Zhou Dynasty. The original meaning of "Yu" is a carriage or sedan chair, and the person driving the sedan chair is called "Yu Man", and later refers to the ordinary people at the lower level. There is a vicious circle between ancient state power and public opinion: the weaker the state power, the stronger the complaints; The voice of complaints and criticisms is becoming more and more fierce, and the situation in the country is declining. It was not until the country changed hands and the regime changed that public opinion came to an end.

Internet public opinion is simply the opinions and comments of netizens, and more directly, it is the subject of netizens' criticism and questioning.
