XINHUA - Feb 28 - On stage, girls wearing masks take turns introducing themselves, and men, sitting behind two lines of desks, express their interest by turning on a light on their desk. This is a dating event held at a matchmaking service center in south China's Guangxi Zhuang Autonomous Region. Since opening in 2015, the center and its founder Pang Yufang have seen 2k people find love. In Pang's service center, ~40K people have signed up, and ~300 volunteers work to examine and sift through the documents. Volunteers at the center are mostly retirees like Pang, who are keen to help young people find love.
