我同意。

I was just trying to dig into what OP meant by "Taiwanese" as a language.

It's always going to be Mandarin for anything commercial.

That said, you can't deny the benefit the Hakka and Hokkien diaspora provided to China's manufacturing capacity - it was diaspora Chinese from Thailand (CP Group was the first foreign private company to incorporate in China), Malaysia, Singapore, Indonesia, and Taiwan had on PRC's catchup.

In Taiwan it’s called Taiwanese. It’s similar to Hokkien which is why it’s often referred to as Taiwanese Hokkien. But it’s not 1:1. And people outside of Taipei will assume you speak it and understand it.
