Is lactose intolerance common in Taiwan?

Coming from America where it’s fairly common for Asians to develop lactose intolerance later in life.

Many of my relatives here are shocked when I tell them, so I’m wondering if it’s an American thing or a generational phenomenon!

Adding on, while I am not vegan, if anybody has recommendations for vegan/ non-dairy desserts or recs, that would be greatly appreciated! :)

I’m sad there don’t seem to be a lot of dairy alternatives for milk tea here.
