Emergency responders rescue a Chinese man caught in a blast that ripped through a Shandong province factory on Monday.
The explosion in Zhangqiu City killed at least 13, while 19 others were injured.
Rescuers at the site on Tuesday searched for the remaining 10 who are still listed as missing, according to state media.
A total of 42 people were caught in the blast at an explosives manufacturing plant.
China has a long history of industrial accidents due to poor safety standards and rising costs of labour and materials.
This comes despite efforts from the ruling Communist party to improve workplace conditions for an estimated 150 million Chinese migrant workers.
