What did China think of homosexuality in ancient times?

In ancient China orthodox thinkers, they can't find any discussion about homosexuality. In this regard, some scholars believe that this shows that they put homosexuality at the end of social problems, which is irrelevant and insignificant in the whole moral system:

Homosexuality was widespread in the pre-Qin period, but a hundred schools of thought generally paid little attention to this social phenomenon, which refers to homosexuality in the general sense among ordinary members of society and rarely made comments. This shows that they put homosexuality at the end of social problems and think that people only need to adjust their reactivity spontaneously, and do not need to study and formulate norms with systematic and profound theories. ..... Confucianism is a combination of morality and politics, and Confucianism does not talk about masculinity, which actually means that homosexuality is irrelevant and insignificant in the whole moral system. (Zhang Zaizhou's "The Course of Ambiguity")

Moreover, not only orthodox thinkers don't talk about homosexuality, but also the classics devoted to sexual issues in the room. However, it doesn't mean that the ancients in China didn't talk about homosexuality. In China's ancient note novels, we can see many comments about homosexuality, but most of them are condemned and denied. For example, Shi Baodao in Ming Dynasty, Silent Drama in Qing Dynasty, Wild Sour Dew Talk, etc. There are some other voices, such as the novel Newly Carved Articles of the Ming Dynasty.

However, although China opposed homosexuality in ancient times, it was basically regarded as a matter of personal moral cultivation, and it was rarely regarded as a crime. Historically, there were laws and regulations prohibiting homosexuality in Song, Ming and Qing Dynasties, but not only the punishment was very light, but also it was rarely implemented.
