Every Saturday and Sunday from noon to 5 p.m., a corner of People’s Park in Shanghai, China, transforms into the long-running Shanghai Marriage Market. Hundreds of anxious parents of unwed adults gather here in search of potential mates for their offspring. They hang listings on the park walls and tape them to open umbrellas, advertising their single kids’ age, height, weight, education, career, salary, zodiac sign, and most becoming personality traits. Moms and dads browse the ads posted by other parents and strike up a conversation if they think their children—and families at large—might be a good match. Many of the unmarried adults being advertised are embarrassed by the practice, or aren’t even aware it’s happening, but that hasn’t slowed the popularity of the market among a certain generation of matchmaking traditionalists. If you attend, be respectful in your observation. They’re not too keen on intruders.
