How did China recover its previous lost territory?

The question is not specific.

Lost territories, both native and subject.

Vietnam, which became a native during the Qin Dynasty, was lost in the middle of the Ming Dynasty and became a vassal state; In the late Qing Dynasty, it lost its vassal state.

Korea, for most of its history as a vassal state (the Han Dynasty became a mainland for a period and later changed to semi-independent), the Qing Dynasty lost its vassal state and was occupied by Japan until it became completely independent after World War II.

Ryukyu State, a long-term vassal state. After the Qing Dynasty, it lost its vassal state, and Japan invaded and occupied it, but its status is unknown. Until the victory in World War II, the United States had suggested that China take it back, but the authorities had more concerns, so the United States took care of it.

Later, in order to counter the Soviet Union, the United States supported Japan, and the Ryukyus officially became Okinawa Prefecture, a Japanese territory. As a result, the issue of the Diaoyu Islands has come to the fore.

Outer Mongolia, the situation is complicated. Before the Tang Dynasty, the Central Plains court did not care about the Mongolian plateau. The main force of the Xiongnu went west, and the southern Xiongnu went south, and the plateau was empty for a time.

The Song Dynasty was turbulent, and the Mongols started on the plateau, and later settled in the Central Plains and became the Yuan Dynasty. The Ming Dynasty defeated the remnants of the Mongols, and the Mongolian Plateau was once again fragmented, gradually surrendering to the Ming Dynasty, which was equivalent to the status of a vassal state. The Qing Dynasty encircled Mongolia, known as the Manchu and Mongolian families, and Mongolia was attached to Mongolia and became a local autonomous region.

After the Xinhai Revolution, Outer Mongolia gradually separated, and was officially separated after the victory in World War II.

The local area is not divided: 1. The part west of the Green Ridge was developed by the Han Dynasty, and the Tang Dynasty continued to be managed by the Western Regions Protectorate. The Qing Dynasty lost the Treaty of Nebuchu and was occupied by Tsarist Russia.

2. Outer Khinganling and Sakhalin Island were originally Xianbei areas. During the Northern and Southern Dynasties, the Xianbei people went south to establish the Northern Wei Dynasty and had close ties with the Central Plains court. to the Qing Dynasty lost.

When? In ancient times, it was solved by force, such as the northern attack on the Xiongnu during the time of Emperor Wu of the Han Dynasty. In modern times, there have been armed forces and agreements, and Taiwan was taken back by the Potsdam Conference.

Engage in hegemonism? It takes a long time.

Xia Dynasty Shao** State, Yue Wang Goujian, Han Wu Emperor Liu Che, Han Guangwu Emperor Liu Xiu, Tang Taizong Li Shimin, anti-Japanese famous generals Qi Jiguang, Zuo Zongtang recovered Xinjiang... King Charles VII of France, Peter the Great reconquest of Finland, Charles de Gaulle reconquest of France... Recently, Putin regained Crimea

When our military power surpasses that of the United States, it will be time to regain lost ground.

Truth, only within the range of artillery.

So now, we can only take a low-intensity way to protect our territorial sovereignty. Because in the event of a war, it can break our rare development opportunity, which is also what the United States hopes for the most, so it will intervene in the disputes between the East China Sea and the South China Sea.

The root cause of all problems is actually the confrontation between China and the United States.

And low-intensity behaviors are better, such as the current land reclamation from the sea, which turns reefs into islands.

As for the time to be strong, I personally think that it will be at least another twenty years.

Strengthening the country is not something that can be achieved overnight.

There are a lot, but as far as the current goals are concerned, Mongolia, southern Tibet, the Ryukyu Islands, the South China Sea Islands, and Taiwan are the most urgent places to recover, after all, now is not the time to turn the other cheek with Russia, and Siberia and other places forcibly occupied by Russia should be delayed, wait for the opportunity, and strive for a one-time solution.

In addition to Taiwan, there are also some islands in the Diaoyu Islands and the Nansha Islands, and I have forgotten what they are called.
