The Supreme Court's historic ruling favoring same-sex marriage throughout the United States last Friday drew celebration in the U.S. and comments from millions of Chinese internet users.

After first hearing the news, many Weibo users had the same reaction as this one person did: "Same-sex [marriage] is legalized in the U.S., it's very shocking news! o(︶︿︶)o"

Same-sex marriage hasn't been legalized in China. It remains common for LGBT Chinese people to enter into heterosexual marriages and live their lives hiding their identities, fearing social stigma.

The pressure comes from the traditional idea that one has to have children to fulfill one's obligations in life, a philosophy that dates back to ancient China. Mencius, one of China's most renowned philosophers after Confucius, is known to have said, "There are three ways to be unfilial; the worst is not to produce offspring."
