It can't be blocked under normal circumstabces, only in the films it was shown to be able to. In the books the only ones who blocked it were Dumbledore and Harry. Dumbledore was using the most powerful wand in the world and he's also the most powerful wizard in the world, so he was able to make it so that it would be blocked by enchanted objects. Sure one could duck behind something, but that's not the same as it being blocked.

Harry was able to block it because of the twin cores his and Voldemort's wand shared. Wands with identical cores can't work against one another. The other times were also under unusual circumstances. Harry's wand worked against Voldemort again because it saw him as an enemy (yeah, I can't really explain it too well). Then the third time he was able to block it because Voldemort tried to use a wand that was in allegiance with Harry (Harry was the true owner). That wand was the Elder Wand, so it wouldn't work against Harry either since he was the true master and it turned on Voldemort.

Zhao would lose, because wizards do have a way to make it so they are invulnerable to flames. Plus they can use cursed fire which can't be stopped or blocked by any non-magical methods.
