In the novel, people with different surnames would often feel that they were slaves with three surnames. This was because in ancient times, people usually regarded surnames as a symbol of status. Having a specific surname meant that this person was the descendant of a certain family and had certain inheritance rights and privileges. If a person traveled to ancient times and found that he did not have a surname but was randomly assigned a surname, he might feel uneasy about his identity and lack of a sense of belonging. Because he did not have his own surname, he could not prove which family he came from, nor could he obtain the corresponding inheritance rights and privileges. In addition, because ancient society paid great attention to family and different bloodlines, there were often some traditional rules and etiquette between surnames. For example, some family members might hold certain positions and responsibilities, and these positions and responsibilities were often determined by the power and status represented by the family name. Therefore, people with different surnames in the novel may feel that they are slaves of three surnames because they don't have their own surnames and can't obtain the corresponding identity and status recognition. This may have a certain impact on their role-playing and character emotions in the novel.
