In 1963, however, a British report on homosexuality and prostitution said individual immorality should not be regarded as a crime punishable by law. In the more than half a century since then, campaigns for equal rights for gays and lesbians have achieved great success. In 2004, gay and lesbian couples could register as legal partners. In 2006, gay and lesbian rights were extended to the filed of business: the Equality Law stipulates that businesspeople should not treat gays and lesbians differently when providing commodities and service. And in March 2013, Queen Elizabeth signed a bill legalizing same-sex marriage in England and Wales.

Although lesbians and gays in Britain and other Western countries still face harassment, and even violence, sometimes, they are rarely discriminated against in workplaces or other spheres of life.

When I worked in China, I seldom observed gays and lesbians being discriminated against at the workplace. But still there is no law or regulation in China to safeguard gay and lesbian rights, which prevents many of them from making their sexual orientation public.

Moreover, the condition of gays and lesbians is not so good in China's middle- and small-sized cities, not to mention rural areas. A few years ago, a lesbian couple in China's southern region received a lot of criticism for organizing a wedding ceremony for themselves. They even had to change their jobs after their sexual orientation became public knowledge.

Gays and lesbians have won equal rights in many Western countries after decades of struggle. Perhaps they have to continue their struggle for some more years in China to get their rights recognized by law. But given that common people's attitude toward gays and lesbians has undergone a great change in big Chinese cities, it is likely that this will happen sooner rather than later.
