The reason why the seal is framed in red has nothing to do with China people's taboo to use red framed names. When using a seal, it is usually stamped by a person or institution with status to prove the validity or legality of the document, so it is very important to use red and boxes to show its status and authority. In ancient times, handwritten red names and boxes were reserved for criminals, so they were regarded as disrespectful. In addition, there is a superstition that there is a life and death book filled with the names of all the people in the world. If a horrible person thinks it is time to end his life, he will draw a circle with a red pen, so writing someone else's name with a red pen is equivalent to cursing others, which will shorten his life or bring bad luck. This is why the red pen can't write his name.
