What kind of person is Xiaohong in a dream of red mansions?

Xiaohong was originally named Lin Hongyu, but was renamed Xiaohong because a word "jade" offended Jia Baoyu and Lin Daiyu. Xiaohong is more alert, especially to Wang Xifeng, who is described by Qingwen as "climbing high and looking far". But who doesn't want to have better development space? There are Qingwen, Musk Moon, etc. Except for xiren, it's not Xiaohong's turn at all, and she doesn't even have the job of serving tea and water. However, Xiaohong still has a conscience, or more accurately, a person with "humanity". After the downfall of Jia Fu, she and Jia Yun can help Baoyu with their meager strength, which shows that they are the most affectionate people.
