Understanding your needs, I will try to create a new article that is different enough from the original content to reduce the similarity. Here's what you've recreated according to your requirements:
The suspense hook at the beginning: "Have you ever wondered how a once glorious island has become a pain that cannot be ignored in China's modern history?" This story not only reveals the tragic history of Sakhalin, but also makes us think about the cruelty of history and the fate of the nation. Today, I will take you into this forgotten corner of history and uncover an untold truth. ”
Hook in the middle paragraph: "Sakhalin, once the gateway to China's northeast, has now become an indelible pain in China's modern history." In 1860, with the signing of the Sino-Russian Treaty of Peking, this rich land was ceded to Tsarist Russia. For China, this is not only a loss of territory, but also a trampling on national dignity. After the occupation of Sakhalin by Tsarist Russia, a brutal rule began. They deprived the Han people on the island of land and property, and brutally oppressed and exploited them. The Han Chinese were forced to serve in the service of Tsarist Russia and suffered inhumane treatment. They live in harsh conditions, with scarce food and rampant diseases. Many people fled because they could not bear the suffering, but many more had to endure it in silence. ”
