The blast, which comes three weeks before the Lunar New Year holidays, occured in an abandoned kiln that was being used illegally to make fireworks, said Xinhua.
The owner of the plant said 16 people were working in the plant on Saturday when it exploded, wounding another two people.
Local police have detained the owner of the operation and are investigating the explosion, said Xinhua.
China invented the fiery displays more than two thousand years ago, but a lax regulatory regime has failed to catch up to a deadly cottage industry that springs up every year as people try to earn a few extra dollars for the holidays.
