It's just a metaphor for the importance of Taiwan Province Province. Taiwan Province Province controls the Strait of Taiwan Province Province on the west coast of the Pacific Ocean and blocks ships from passing through the Straits of Malacca. It can't make ships go northward, covering the East China Sea and the South China Sea centered on Taiwan Province Province. If there is a war in the Indian Ocean, you can immediately support it.

Once Taiwan Province Province falls into the hands of foreign enemies and separatist forces, Taiwan Province Province will not only lose its barrier function, but also open the door to Chinese mainland, and the whole maritime strategic defense will lose its depth. Moreover, the capital of Taiwan Province has further become a springboard and stronghold for foreign enemies to attack the mainland, growing like a cancer in the abdomen of the mainland, seriously endangering the survival of the whole country and nation.

Taiwan Province Province is located at the core of the first island chain.

It is a strategic seaport for our army to enter the eastern Pacific.

Its eastern sea area is an important channel for China's maritime transportation.

It is a natural barrier along the eastern coast of China.
