Bisexuality and homosexuality in Ancient Greece is (relatively) well-documented and understood, but same-sex love and romance in Ancient China is a little more complex and speculative.
Still, there is recorded documentation of same-sex relationships in each of Ancient China's many dynasties, and there are many things we know about how bisexuality manifested itself during those times. Similar to Greece, there wasn’t a strict divide between “gay,” “straight,” and “bisexual," and in Ancient Chinese times, it’s believed that same-sex relationships were more commonplace.
To increase your knowledge of queer history, here’s some factoids about bisexuality and homosexuality from the time of Ancient China. (Unsurprisingly, many of the historic accounts of homosexuality take the form of stories/myths, so we’ll share some of those too.)
