Understand the background of the Opium War, observe the history of China in the world environment, and reveal the root and inevitability of the outbreak of the Opium War. At the same time, we should realize that it is shameful for Britain to launch a war to protect opium smuggling and open the door to invade China. It is in China's national interest that Lin Zexu led the anti-smoking movement and destroyed opium in Humen's just act. Understand the direct cause and inevitability of the outbreak of war. Grasp the great historical significance of the anti-smoking movement and the destruction of opium in Humen, the reasons for China's defeat in the Opium War and the contents of the relevant treaties signed. The Second Opium War was another war of aggression against China launched by Britain and France in order to expand the rights and interests of aggression gained in the first Opium War and further open the China market, which was essentially a continuation of the Opium War. The Second Opium War not only deepened the degree of semi-colonization of China society, but also contributed to the collusion between Chinese and foreign reactionary forces.

Understand the Ma Fu incident, grasp the root of the Second Opium War, the course of the war and its serious harm to China, and understand the reasons for China's defeat. Connecting with the criminal facts of foreign religious forces in China, we can further understand the essence of colonial cultural aggression under this religious cloak.

Geography: Understand the process and route of the two Opium Wars, the main locations where China's military and civilians fought against aggression, and the geographical locations of ports and concessions that were forced to open after the war.

Connecting with the geographical position of the "Golden Triangle" area in Southeast Asia, one of the drug producing areas in the world today, we can master the natural conditions for opium cultivation in this area.

Politics: Through the understanding of the root and direct causes of the outbreak of the Opium War, we can understand and master the philosophical truth that "the inevitability of historical development is expressed through contingency". Using the method of "seeing the essence through the phenomenon" to understand opium smuggling and opium war, combined with the current events of combating drug crimes in the world, we can understand the necessity and significance of drug control from the perspective of national nature and national function. At the same time, the younger generation should establish a correct consciousness and attitude of "staying away from drugs and refusing drugs".
