All of the china marble and granite i have seen is clearly marked as "Indoor
use only". It is low grade and not likely to survive a few freeze thaw
cycles.
DON'T BUY/TRUST ANYTHING MADE IN CHINA!

"I thought granite behaves well in winter."

That's where sand comes from. It naturally spalls and erodes from the
surface of granite rocks due to a number of processes of which freeze/thaw
is one.

Not to say your stone will fare poorly, sealing it will help ensure the
surface stays polished. Cracking should only occur if your substrate is
insufficient and moves for amy reason.
