The international community designated June 3 as the "International Anti-Drug Day" and then June 26 as the "International Anti-Drug Day". What events in China are these regulations related to?

June 3rd and June 26th are both designated as "International Anti-Drug Day", which is related to the famous anti-smoking campaign of the Qing Dynasty in China - Humen Smoking.

From June 12 to 26, 1987, the United Nations held a Ministerial Conference on Narcotic Drug Abuse and Illicit Trafficking in Vienna with the participation of more than 3,000 representatives from 138 countries. The meeting put forward the slogan "Love life, don't take drugs". Representatives at the conference unanimously agreed to designate June 26 every year as the "International Anti-Drug Day" to draw the attention of countries around the world to the drug problem and call on people around the world to work together to solve the drug problem.

In China, International Anti-Drug Day is linked to the famous anti-drug operation of the Qing Dynasty - the historical event of Humen Destroying Opium.

On June 3, 1839, 160 years ago (i.e., April 22nd, Jihai, the 19th year of Emperor Xuanzong of the Qing Dynasty), national hero Lin Zexu ordered the destruction of opium on Humen Beach. Ends June 25th. The elimination of opium in Humen became a historical event in the fight against drugs. It not only dealt a heavy blow to the criminal behavior of Western colonists who made ill-gotten gains through the opium trade, but also wrote a heroic first chapter in the history of world drug control. June 3, the day when the cigarette smoking ban began in Humen, was later designated as a non-holiday anti-smoking day during the Republic of China, and June 26, the day after the cigarette smoking ban ended, also happened to be the International Anti-Drug Day.
