11/28 afer the nanjing treaty, the china sign the British Supplementary Treaty of the Bogue,Treaty of Wanghia, treaties of Tientsin,Treaty of Aigun. why the europe choose china to actualiza their imperilism? i think the europe should stop selling the opium to china, because the opium is the worst thing in the world, it kills alots of the people and push them to do illegal things cause of they need the money to buy the opium.
