What if I can't understand and imagine the description of clothes and environment in A Dream of Red Mansions?

Cao Xueqin, the author of A Dream of Red Mansions, was born in the Qing Dynasty, when the literary inquisition prevailed. In order to avoid the costume, etiquette and architectural features at that time, he deliberately described the costumes of important people at arm's length, including many fictional elements. It's a bit of a Qing dynasty aristocrat, but it's not so obvious that people conclude that "you wrote about the Qing dynasty" and that "it's just that you lost the exam."

For example, when Princess Yuan visited relatives in the province, she said that Mrs. Jia and Mrs. Wang were "dressed according to quality", but she avoided talking about what "quality" was and how to "dress up".

I suggest to find a book "Qigong tells you about the Red Chamber" (it seems to be this name) to read.

Mr. Qi Gong is a famous calligrapher, redologist and cultural researcher in Qing Dynasty. He himself is a descendant of the Qing dynasty nobles, and he has a very experienced understanding and research on the etiquette, clothing and language of the Qing dynasty. This book has a lot of space to illustrate and explain the clothes of the Qing dynasty nobles.
