"A mooncake for Mid-Autumn Fest." Repeat. Find the rhythm? Can it be more rhythmic? Find the answer this weekend from rappers at Beijing's Happy Valley.

The amusement park will celebrate the Mid-Autumn Festival with China's first ever hip-hop music carnival, park authorities announced Tuesday.

With the traditional mooncake-eating festival falling on a Sunday, Chinese people will get Monday off for an extended three-day weekend. The bonus day comes after the Mid-Autumn Festival was for the first time named as a national holiday.

A line-up of hip-hop artists will join the celebrations. Headliners are local band Yintsang, Chinese-American singer Jeffrey Kung and his band, as well as street-dance group Zoo Nation, who led an eight-minute showcase of London culture at the Beijing Olympics closing ceremony.

Graffiti, the "bling-bling" outfit fashion, and other elements of hip-hop culture, will also be highlighted at the event.
