What's the difference between Mandarin in Taiwan Province and Mandarin in Chinese mainland?

Basically, Mandarin in Taiwan Province Province is no different from Mandarin in Chinese mainland.

In Taiwan Province Province, Putonghua is called "national language" and in Taiwan Province Province, it is called "Taiwanese".

Both "Putonghua" in Taiwan Province Province and "Putonghua" in mainland China are derived from Beijing dialect. Just because it is appropriate, Taiwan Province's Putonghua has a naive suffix, and its tongue volume is not as much as that of mainland Putonghua. In addition, there are some subtle differences in words or pronunciation. For example, "soy sauce" is not a word in Taiwan Province province. The leading role is pronounced "foot" in Taiwan Province province and "absolute" in Chinese mainland.
