As Ahava and Lushun Port are two supply ports in beiyang fleet, China, Li Hongzhang has invested a huge sum of money in these two ports to build them into the barrier of the capital and safeguard the security of the capital. After the Sino-Japanese War of 1894-1895, beiyang fleet was completely annihilated, but the naval facilities in these two ports were still perfect, and warships could dock directly. So these two ports became fat meat in the eyes of the great powers at that time, controlling them, and the door of Beijing was wide open. In the spirit of winning first, Russia took the lead in seizing the port of Lushun, and announced to the public that the northern part of the Great Wall is the sphere of Russian influence. It was this Russia that set off the frenzy of the great powers to carve up China. Russians have all started their work. As the world's number one industrial power at that time, Britain couldn't sit still and couldn't wait any longer, so Britain declared the Yangtze River valley as British territory and asked the Qing government to lease Ahava. At that time, the Qing government sent Li Hongzhang as the plenipotentiary to negotiate with Britain. Although Li Hongzhang has a golden mouth and jade words, a weak country has no diplomacy. British negotiators said that as long as Li Hongzhang could persuade Russia to give up leasing Lushun Port, Britain would give up leasing Ahava. So Ahava was leased to Britain, and it was not until Chiang Kai-shek's government later that the government of the Republic of China negotiated with the British government and abolished many unequal treaties that it gradually recovered its sovereignty over Ahava.
