In the 18th year of Daoguang 1 15 10, Lin Zexu was appointed as an imperial envoy to investigate and punish smoking ban in Guangzhou. In the 19th year of Daoguang (1March, 839), he arrived in Guangzhou in the first month, and on the fourth day of February (1March, 9), Lin Zexu, together with Deng Yanzhen and others, summoned thirteen foreign businessmen, ordered them to hand over their letters, ordered foreign opium dealers to pay cigarettes within a time limit, and made a promise that they would never carry opium in the future.

However, foreign businessmen refused to hand it over. After resolute struggle, they defeated the British commercial supervision law and opium dealers in China, and confiscated nearly 20 thousand boxes of opium, about 2.37 million kilograms. On April 22nd (June 3rd), it was destroyed in public at Humen Beach.

Second, look at the world

He put forward the idea of "learning from foreigners to control foreigners", and he put forward the idea of building guns and ships to change the backward state of military technology; He personally presided over and organized the translation team, translated foreign books and periodicals, and translated foreigners' remarks about China into Petrochemical Yi Yan as the official "reference news" of China at that time.

To meet the needs of the struggle against the enemy and foreign negotiations at that time, the author quickly compiled International Law, which was an epoch-making event in the history of international law in China: it marked the beginning of the formal introduction of western international law works into China, the beginning of the application of modern international law to China's foreign negotiations, and the beginning of China's modern international law history.

Third, water conservancy management

In the 11th year of Daoguang (183 1 year 65438+ February 25th), on November 22nd, Lin Zexu was promoted to Governor of Donghe. After Lin Zexu took office, he immediately made up his knowledge of water control, inspected river workers, maintained quality, punished officials who failed in their work, and ordered the inspection of river embankment piles.

In his memorial to Daoguang, he said: "The weekly calendar survey is always carried out in each crib, measuring the height, width and scale of each crib, comparing its old and new reality, drawing if it is loose, disassembling if it is doubtful, bundling according to the crib and weighing according to the bundle. There is no unexpected stack, and there is no hall that cannot be dismantled.

Fourth, settled in Shaanxi.

In July of the 26th year of Daoguang, after Lin Zexu became the governor of Shaanxi, he wrote to the emperor, declaring that Shaanxi "is adjacent to Shanxi and Henan in the northeast, Sichuan and Gansu in the southwest, with different roads, and traitors are easy to haunt. If you are a knife bandit with a murder weapon, running away with this will do the greatest harm to the people. " He also expressed his determination to "eliminate violence and peace" and "strike hard at local calm" as the "primary task" after taking over as the governor of Shaanxi Province.

By the end of the year, due to Lin Zexu's active supervision and suppression, 146 people were captured successively in eastern counties of Guanzhong and Ansai county of northern Shaanxi, among which 46 people were clearly called "knife bandits" and were severely punished. Zhu Pi, Emperor Daoguang, praised Lin Zexu for actively suppressing swordsmen.

Verb (abbreviation of verb) defends Xinjiang.

Despite his advanced age and declining physical strength, Lin Zexu visited eight cities in southern Xinjiang from Yili to "Three Wan Li in the Western Regions", which deepened his understanding of the importance of border defense in northwest China. Lin Zexu's translation materials found that Russia threatened China, which prompted him to resist Britain's and Russia's national defense thought and became the pioneer of modern "anti-blockade theory".

Therefore, he clearly proposed to the Ili general Bu Yantai that he should prepare for the "battle of ploughing". He also led the masses to build water conservancy projects and popularize karez and spinning wheels. People call it "Lin Gong Jing" and "Lin Che" to commemorate his achievements.
