"My child and many other gay kids are wonderful people," she insisted. "They should have the right to get married and adopt children."
In China, having children out of wedlock is illegal.
The legalization of same-sex marriage has been a hot topic on Chinese Internet sites during this year's annual session of China's legislature.
QQ.com, a popular instant messaging site, has published a survey asking whether same-sex marriage should be legalized. 20,518 voted yes. 1,992 voted no.
One user, using the online name Zhangsichen, wrote on Weibo, China's version of Twitter, "Everyone has the right to love and be loved. True love should be accepted. You can choose not to accept it, but you don't have the right to interfere with the freedom and rights of others."
On the other side of the argument, a user named Guo Jiani wrote, "We need to distinguish between right and wrong. We can't categorize wrong as right out of sympathy. If the world is full of gays, then we won't have a next generation, and the world will become evil."
There is still no news from the government about the proposal's fate.
Li Yinhe, a sexologist from the Chinese Academy of Social Sciences and a promoter of LGBT rights, asked deputies to submit a proposal to the legislature to legalize same-sex marriages. But she couldn't find the minimum of 30 deputies needed to table the bill. The members rejected her by saying they were "not familiar with this topic."
"It is a very good sign that the Chinese media are discussing this topic openly and positively this year," Li commented. "Usually, the government would warn the media not to mention a word about this topic. But there is still a very long way to go before we legalize same-sex marriage."
Since accepting her son's sexual orientation, Wang has spent her spare time on the Internet reading the stories of gay and lesbian children, and helping their parents to understand and accept them.
Her husband divorced her, remarried and had another son.
"He could never accept that his son is gay," she said.
