And in all of those places you'd usually noted how bad is the taste of water, so many people knew it's unsafe not just from tradition, but also from the bad taste. The difference between now and medieval England is that we know taste is not everything, that even "sweet water" can be dangerous unboiled.

Considering the strength of the Chinese taboo on cold water, I find that fairly unlikely.

My understanding is this is rooted in the perception of hot water as a luxury—it's not like we have any shortage of evidence from chinese texts that people have always drank cold water. The idea that most people even could avoid cold water is an artifact of the last two centuries. Even where boiling water was necessary water was boiled and stored (that's not specific to my knowledge of China, that's just an observation from multiple different places and times).

Of course I'm open to be demonstrated wrong.

We often say that the US are not the world and that we should not assume that something is natural just because American do it. Well, it’s also true for China and overall people in a specific place having a specific taboo tells us very little about human health or their understanding of it.

So no, a Chinese taboo on cold water does not tell us anything about a human tendency to drink water any more that a people’s taboo about pork is any indication that pork is unsafe (yes, this also is an urban legend).

People in a specific place having a specific taboo can tell us a lot about how likely they are to engage in the tabooed behavior. The argument was that people in China would have noted the bad taste of their raw water. In order to do that, they would have had to drink it, which I find unlikely.
