What are the taboos for writing with a red pen? What's the point of writing with a red pen?

1, our country folk known as "Dan Shu ominous" said. 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 a brush, and those who crossed it out with calligraphy were undoubtedly sentenced to death. So far, 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 has been a tradition 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.

2. Because some people feel guilty about writing with a red pen, which leads to friends breaking up, there is another saying that writing with a red pen means breaking up.
