After the Taiwanese Constitutional Court ruled in May 2017 that banning same-sex marriage is unconstitutional under the Constitution of the Republic of China, attitudes were largely positive on the popular Chinese social media site Sina Weibo. Sociologist Li Yinhe claimed that a majority of Chinese people under the age of 35 approved of same-sex marriage. Pointing out that the average age of members of the National People's Congress is 49, she concluded that same-sex marriage is "only 14 years away". However, the Chinese Government moved to censor any news of the court ruling, not because of the issue of same-sex marriage but because of the "alleged illegality of Taiwan's courts". Days after the same-sex marriage law came into effect in Taiwan in May 2019, the "People's Daily", the Communist Party's newspaper, posted a celebratory tweet, "local lawmakers in Taiwan, China, have legalized same-sex marriage in a first for Asia." The tweet, which included a rainbow-colored GIF that read "love is love" angered the Foreign Minister of Taiwan, Joseph Wu, who retaliated, "WRONG! The bill was passed by our national parliament & will be signed by the president soon. Democratic #Taiwan is a country in itself & has nothing to do with authoritarian #China. @PDChina is a commie brainwasher & it sucks. JW." Nonetheless, Chinese authorities signaled that it would not follow Taiwan's example on same-sex marriage. An Fengshan, spokesman for China's Taiwan Affairs Office, said the Chinese Government "noted reports on the island" about same-sex marriage and that "the mainland has a marriage system of one man, one woman".
