Like other answers from previous threads have stated, the concept and the label of "homosexuality" did not exist until much later in history (example one, two, and three), so without the influence of Abrahamic religions we rarely see laws or morality codes explicitly tolerating or outlawing homosexuality in particular. That being said there are many historical examples of homosexuality in ancient China. The most famous one would be between Emperor Ai of Han and politician Dong Xian. According to Book of Han, Dong was granted many favors and quickly rose from obscurity as a minor official to being the most powerful official in court at age 22. The most famous legend describes Dong fell asleep on the emperor's sleeve (robes at the time had a very large kimono-like sleeves). The emperor did not want to wake Dong so he cut the sleeve off his robe instead. "Passion of the cut sleeve" became a euphemism for people engaging in homosexual sex. Others resented Dong not because he is gay, but because they felt he has been granted too much power unfairly.

In Chinese folklore there is a deity called Tu'er Shen (literally "Rabbit Deity) who manages homosexual affairs between men. According to Qing Dynasty writer Yuan Mei's collection of folklore (the book is called What the Master Would Not Discuss), a man named Hu Tianbao was sentenced to death for peeking at a handsome imperial official. He later appeared in the dreams of village elders and demanded a shrine be built.
