Culturally speaking, we may still have strong tie with Hans.

However, as for ethnic origins, we certainly have intimate connections with 台灣原住民.

Most importantly, Taiwanese heart and soul seem closer to 原住民 than to Chinese.
For example, we like simplicity rather than sophistication when we are with others.
We are friendly and enthusiastic rather than defensive and indifferent to strangers. I would say Taiwanese may be greatly influenced by 原住民 if not inherit the above characteristics from them.
