Li Ruiying is a female anchorwoman of the program News Broadcast. The other day, Li Ruiying appeared in Sichuan Normal University to deliver a special lecture on "the Responsibility and Commitment of Media". She disclosed that CCTV was very strict with anchorwomen's slip of tongue. Li Ruiying said that "the slip of tongue of the anchorpersons of the program News Broadcast was divided into four categories: A, B, C and D. The most serious Category-A error was called the "death penalty". If an irretrievable mistake occurred, the anchorperson would be required to leave his/her post after the news broadcast the next day."
