Outdoors of "Today Art Museum"

It's not obvious, but
it's huge

While biking back from trip, I've found there are more sculptures, hidden between buildings.  Unluckily, at that moment, my phone was dead and not kicking. But, strong in resolve to take photos, I returned next day. Behold, here they are!

As usual, I have no idea what they mean or who made them, and there was no backstory on any of them :).
