Hong Kong Macau Republic of China (Taiwan)(groups of pro-Chinese identity) Hong Kong Republic of China (Taiwan)(groups of pro-Chinese identity) Current Former Li Yinhe (simplified Chinese: 李银河; traditional Chinese: 李銀河; pinyin: Lǐ Yínhé; née Li Sanfan; born February 4, 1952) is a Chinese sociologist, sexologist, and activist for LGBT rights in China.

Li and her brother adopted their matrilineal surname as a realization of their parents' ideas of gender equality.

In 1979, Li joined the newly-founded Institute of Marxism–Leninism at the Chinese Academy of Social Sciences, where she researched marriage and family issues.

[3][2] In the 1990s, as part of her research on homosexuality, Li began to translate many important texts focused on queer theory.

Li also publicly speaks about other issues of social justice, such as the growing urban-rural divide in China.

[8] Li called on legislators to legalize pornography,[2][9] abolish the group licentiousness law[2][10] (which provides up to five years in prison for consenting adults who have sex with more than one other person), and decriminalize prostitution.

[1] Since 2002, Li has continued asking members of the National Committee of the Chinese People's Political Consultative Conference (CPPCC) to submit her proposal.
