Police in Guangdong have confiscated over 760-kilograms of materials connected to methamphetamines, arresting 52 people in connection with making the drugs.
The crackdown in the city of Jieyang and areas around it have involved more than 400 police and firefighters.
Authorities became suspicious after locals reported a sour smell coming from a property.
"We smelled the specific odor which is normally associated with the production of meth. We went in and found the drug den was in a three-bedroom house. Several people were working there. The police immediately detained the suspects and found the raw materials and tools for making the drugs in the subsequent inspection."
The southern province of Guangdong has become a hub for the production of methamphetamines here in China.
Provincial authorities have launched a wide-spread crackdown on the production and distribution of "ice."
