Why is Chen Qianqian a princess and her two sisters are princesses? Judging from the storyline, as the audience, we all found that the original hostess of Huayuan City, among the three daughters, likes the third daughter Chen Qianqian best, and the two sisters are also modest and indulgent to this charming and wayward sister, so Chen Qianqian herself calls herself the Princess of Huayuan City, and no one specifically corrects and questions it.
As we can see from the beginning of the series, Chen Qianqian came to Huayuan City in Lu Yu, and the second princess Chen Chuchu of Touy liked it very much. She robbed people in the street without telling her sister beforehand, but her sister was not angry when she knew about it, which shows how Chen Qianqian existed in Huayuan City.
Secondly, from the perspective of role setting, the second sister Chen Chuchu is nominally the daughter of the duke, who is very experienced in martial arts and managing the people in the city, but she is not the duke's own daughter, which is a thorn in Chen Chuchu's heart, so the second sister Chen Chuchu is just a monarch, which is also the main reason why Chen Chuchu became black in his later period and Chen Qian never died.
Sister Chen Yuanyuan is actually a very talented woman in my eyes, but she is full of doubts. She knows medical skills, but she can't cure her leg. She didn't begin to save her love until the situation was stable in the later period, which shows that she was hiding her strength in the early stage and was called the monarch without deliberately emphasizing it.
Finally, from the ancient system, it can be seen that only the emperor's daughter is qualified to be called a princess, or a princess will be awarded a commission to show the court's attention. Generally, she can only be called a princess. So, Chen Qianqian unceremoniously claimed to be Yincui gorge. As soon as she appeared in the city, she knew how headstrong Chen Qianqian was.
