Wow, you're so skilled at missing the point entirely. Either you didn't read any of my previous comments or you have selective amnesia.

When you call the A/C repair man, he doesn't have to rebuild your entire house just to make it compatible with A/C.

Not to mention, you're the one calling him in; not some imperialistic nation-state actor guilty of cultural erasure of virtually every ethnic minority group within their own borders.

You have yet to answer how A/C is going to protect people in open-air houses from the effects of climate change. This magical "China will save them" is a silly utopian fantasy divorced from reality.
