On March 10, 1839, Lin came to Guangzhou with the official seal issued by Emperor Daoguang and the military leadership of Guangdong navy, beginning world-famous anti-opium activity. Lin once destroyed more than 20,000 boxes of opium in Humen town, accounting for more than half of the opium smuggled to China. Lin won the unprecedented victory in the history of anti-opium and first pushed the anti-opium activity of China to a new high. The destruction of opium in Humen was the great starting point of anti-imperialist and patriotic struggle and also a brilliant chapter in China's history of anti-drug. In this sense, Lin was not only an anti-opium hero but also the first anti-imperialist and patriotic hero in the modern history of China.

This code included anti-opium program and planning.
