1. Reasons for victory

① Support of the people. Opium seriously affects the health of the people, and the people firmly support the ban on smoking.

②The emperor’s support. The importation of opium seriously endangered the rule of the Qing government. Emperor Daoguang sent Lin Zexu to Guangdong to ban smoking and support the anti-smoking movement.

③Lin Zexu’s correct leadership. Lin Zexu's firm determination to ban smoking and his war preparations in Guangdong, etc.

2. The historical significance of Humen’s opium eradication:

1. On the one hand, Humen’s opium eradication awakened many patriotic and far-sighted people at that time, who began to reflect on themselves and reposition China in the world. It no longer regards itself as the "highest country in heaven". On the other hand, it also greatly suppressed the British opium trade in China, dealt a heavy blow to the British bourgeoisie's trade plunder in China, and demonstrated the Chinese people's firm determination and awakening awareness to ban smoking.

2. This incident has also become an example of the anti-smoking movement in the world. In history, many countries and regions have followed this example based on their own circumstances to curb the spread of drugs.

3. The victory of the anti-smoking movement led by Lin Zexu safeguarded the dignity and interests of the Chinese nation. "The elimination of opium in Humen" is an important historical example of China's fight against imperialism in modern history, and it is also an unprecedented feat in human history. Historians believe that it demonstrates the determination of the Chinese nation to oppose foreign aggression and is of symbolic significance to the Chinese people's fight against foreign aggression.
