The Chinese army was ill trained, poorly led, malnourished, and generally disorganized.
The North Vietnamese initially were also ill trained, poorly led, malnourished, and generally disorganized when they started fighting against the French with no one's help.
The Taiwanese do not identify themselves as Chinese, but as Taiwanese.
Here is what one of you guys said last yr...

Chinese american is not Chinese any more.
A Chinese-American is culturally
NON-CHINESE as stated by Mr. wanglaokan there. In the same vein, a person who identifies as a Taiwanese must be rejected by China. A Taiwanese is just as non-Chinese as a Chinese-American. We non-Chinese in this forum did not made it up. One of you did.
That means the Taiwanese will fight. The fact that they spent so much of their hard earned money over these decades cannot be underestimated regarding their willingness to defend their ways of life. Whether the US will assist them or not is for a different debate, but if you are willing to look at the geography in an objective manner, all the US have to do is keep the eastern side of the Taiwan island clear and the Taiwanese will make any invasion practically impossible. You cannot defeat the US Navy and your admirals knows it. You can boast DF-21D all you want and it will be for naught.
You want to convince them to return to China? That is the better way. They want to declare independence? Let them go. You guys already rejected them, right?
