Police in Guangxi Zhuang Autonomous Region of Hechi City also arrested eight drug dealers, while confiscating a vehicle and 200,000 yuan (USD 29,039) from drug transactions.
In September, police received a tip-off about several non-locals making drugs in a remote mountain village in Hechi.
Two months of investigation showed that a couple provided drug manufacturing sites, while other suspects supplied money and drug-producing techniques.
The final products were then sold in Hechi and neighbouring areas, state-run Xinhua news agency reported.
