Why did the Kuomintang choose to defeat Taiwan Province Province after the War of Liberation?

First of all, there is a strait barrier, and both Taiwan Province Province and Hainan can choose; This time, the Taiwan Province Strait is much wider than Qiongzhou Strait, making it more difficult for the PLA to cross. Third, Taiwan Province Province has a certain industrial base with 50 years of Japanese occupation. Fourth; Taiwan Province Province has no * * * organization for a long time under Japanese rule. After the victory of the Anti-Japanese War, the Kuomintang suppressed the only * * * organization in 228, and Hainan has always had the activities of Qiongya Column. In contrast, Taiwan Province Province is much safer.
