Why are tea pickers the protagonists of many poems?

In literary and artistic works, both female images and human nature like to find beauty.

As we all know, in the Qing dynasty, a minority regime and the most self-disciplined dynasty of the royal family, ladies-in-waiting and concubines were not allowed to choose too beautiful things to confuse the sacred heart. So there are basically no beautiful women in the real Qing court, but if you find such a group, I'm afraid no one will watch TV dramas.

In the old society, due to the limitation of objective conditions, it was difficult for working women to be beautiful. No matter how beautiful they were, they turned their backs on the loess and worked in the fields like men for some days. For this reason, when writing about such women in literary and artistic works, most people like to find some technical jobs, such as sericulture, tea picking and weaving. Whether it is true or not, the girl who picks tea is a beauty, at least it sounds more beautiful than the girl who cultivates land.
