I think it’s a trick photo. If I look closely, I can see that in front of the block of ice there is snow right up against the camera, so it looks like the “big block” of ice is actually right up against the camera lens, and the man is standing way in the background. I guess the big block is only a small one, like a few inches tall? Neat trick.
By the way, the Chinese in Northern China are actually a very tall race——on average they are taller than your average white North American, so maybe the ice sculpture is humongous. Lol.
