They do this all the time, but I think this is the only instance I've seen them do it for a whole neighborhood and not just one building. When it comes to construction China has really embraced tech innovations, and for good reason: they had a lot to build in a short time, and still do. They build bridges with a machine as well that lays down prefab pieces of it one by one.

They are not the only country that uses this however, but they've certainly pioneered it and nobody that I know uses it as often as they do in China. Last I checked it was used maybe once or twice in the west to move an old lighthouse, and that's about it lol.

incredible

some more context:

The temporary relocation was initiated to enable the construction of a three-story underground space beneath Zhangyuan, which stands as one of Shanghai's largest and best-preserved shikumen complexes with a history exceeding 140 years.

The underground development, covering over 53,000 square meters, will house cultural and commercial spaces, provide over 100 parking spots, and facilitate connections between Metro Lines 2, 12 and 13.

They walk? Nice!
