Please point out the writing background of Lao She's Sunshine. Thank you!

Reading Crescent Moon and Sunshine in a complementary way, it is found that the theme of Crescent Moon does not fully reflect the change of women's fate caused by poverty. The heroine in Sunshine is very rich, but she also faces the tragedy of the protagonist in Crescent Moon, so the themes of Crescent Moon and Sunshine are to reveal the plight of women in a patriarchal society. For thousands of years, the traditional culture with male power as the core has endowed women with dependent survival norms. In this standard of existence, women can't help but demand their own survival principles from the perspective of men, which leads to the lack of independent consciousness and their own tragic existence.
