But these are not before/after videos, but part of a changed housing and building policy. Urbanization and westernization has gone too far with crowded and polluted cities, logistics like commuting breaking down, factories that cannot export as they used to etc. and large parts of the country lacks people for farming or taking care of of the elderly left behind when the young generation left looking for jobs. See it as instruction DIY videos, see, it can be done this is how, these steps are necessary. And a boast of traditional values and believes. Plus the building industry gets a chance to sell products - cement products or roof tiles for ex. Or handy Chinese electric tools. This video example seems to be about how to salvage old cracked walls instead of tearing them down and buy new bricks ;)

They are more about the work than the result..I think.

I totally agree!!
