According to the administration, it also detected the largest marijuana cultivation area in Jilin province and Inner Mongolia since 1949, when the people's republic of China was founded, and discovered a oil tanker off the coast of Fujian province believed to be smuggling oil on a large scale.

According to the Ministry of Public Security, all the discoveries will be considered "supporting evidence for the relevant law enforcement authorities to conduct further investigations."
