1 Red pen is used for correction. Red, like the color of blood, represents a painful lesson and is easier to arouse people's hearts. Writing with a red pen in homework is disrespectful to the teacher! Writing a letter in red means breaking up! Interviewee: Dong Zhen-Senior Manager Grade 7 10- 14 22:20 There is a saying in China that "Dan Shu is ominous". As we all know, in ancient times, except for the emperor sitting in the golden palace, calligraphy was generally used by yamen to record the names of criminals. There is a saying among the people that Yan Yan crossed out the book of life and death with calligraphy, and those who crossed it out with calligraphy were undoubtedly sentenced to death. Up to now, criminals sentenced to death have marked their names with red "X" or "√", so people are very afraid of writing letters in red, and even more afraid of receiving things written in red. People are forbidden to write in red ink, which is a tradition established for thousands of years. This folk custom has been deeply rooted in people's hearts and followed by people. It can be said that this is just a tradition and habit, not a feudal superstition. Although the red pen plays an irreplaceable role and significance for some needs, it will only be used in some specific occasions, such as teachers marking test papers and doctors canceling medical orders. Because some people are jealous of writing with a red pen, which leads to friends breaking up, there is also a saying that writing with a red pen is breaking up. But personally, I don't think it is necessary to write a dear John letter in red. Isn't there a saying that "it's good to be apart"? The ancients also said, "A gentleman should break up with you, and you should not make an ugly voice." After all, friends are friends, so why not be generous? In ancient times, people wrote letters in red pen to prepare for urgent or important things. Cinnabar was used at that time. Now, one is for beauty, and the other is that writing a letter with a red pen means breaking up.
