You are wrong. Most Chinese here expect US to go to war with China. After Biden said it the 4th time that US will go to war with China over Taiwan, there is no more doubt. However, US navy does not scare China. Going to war with US does not scare China. In fact it is what China is planning for. Just like how US's military spending and doctrine is now all for preparing for a war with China later this decade, China's military spending and doctrine is also focused on winning a war against US later this decade.
Once Chinese are used to a life of comfort it is hard to go to war. It is much easier to go for peaceful reunification route provided sentiment is there on both sides. There is a big question over what happens to the CCP.
It is much easier to wait and to hope for the decline of the USA.
