This user name combines two identities: 'Deer Ten Youth from the Hutong Alley' and 'Cat Seven Maiden from the Street.' This reflects the owner's playful nature, suggesting a young person who loves life in a traditional Chinese neighborhood (hutong) and possibly has a split personality or a dreamlike sense of freedom associated with deer (graceful) and cat (mysterious).
