Li Yinhe, a sexology scholar well known in the Chinese LGBT community, proposed the "Chinese Same-Sex Marriage Bill" (, pinyin: ) as an amendment to the marriage law to the Chinese People's Political Consultative Conference in 2003, 2005, 2006 and 2008. All four proposals failed because she was unable to find enough cosponsors for a placement on the agenda. Li pledged to "continue proposing the bill until it is passed". In 2008, supporters of LGBT rights launched a campaign to collect signatures calling for the recognition of same-sex marriage. In 2012, Li launched a new campaign to raise support for same-sex marriage legislation.
