Chinese police are on alert for firework crimes and violations.
A statement by the Ministry of Public Security on Thursday said that the ministry has ordered police nationwide to intensify checks of illegal production, sales, transport and storage of fireworks and firecrackers.
Chinese people traditionally set off fireworks and firecrackers during the Spring Festival, China's lunar New Year.
The ministry statement said that police nationwide have dealt with 203 pyrotechnic cases since December and a total of 419 suspects have been taken into custody.
The statement also advised the public to reduce the use of fireworks for safety and environmental reasons.
