Zhou Yan (born March 22, 1988), known as "GAI", is a Chinese rapper, singer, and songwriter. He achieved a meteoric rise from a contestant on a rap show to become the most successful hip hop stars in China today, and is partially responsible for the rise of the genre itself. His stage name GAI is a childhood nickname meaning "lid" that he was given because of his bowl cut. In 2017, GAI's music career began to boom after attending iQiyi's Hip-Hop reality show The Rap of China, and winning the contest. In 2018, he married his girlfriend Wang Siran.
