Southern China - where I had a lot of concerns - is stable and even boring at the moment. The weather halted the Japanese advance and they don't have an HQ down there, so advancing inland is virtually impossible. Meanwhile I railed a couple of more defenders south and moved a couple other units by land. That all was possible because there is no Japanese threat in central China (as can be seen in the screenshot below).
Because the USSR has all its eastern Asia forces gathered on the border west of Vladivostok, Japan is keeping 5 or so units (but no HQ's) in Manchuria. You can see the HQ wandering southward in the screenshot. This makes for 3 Japanese HQ's in northern China, plus all their air units.
This is still the first turn and we are in the 9th impulse. The chance of the turn ending is 30% for the Allies and, should that not occur, it will be 50% for the Axis ending the turn after impulse #11. Note the weather probabilities in the upper right for the impending Axis impulse. And the destroyed pool in the lower left corner. The Germans lost an Inf attacking Lodz (1/1 result) and they shot down a Brit carrier air unit using their Naval Air unit for a strategic bombing mission in central England. About that, the carrier air unit had a range of 4 so it was able to fly inland 1 hex from the coast - which was brilliant, but disastrous. The bomber was cleared through but its bombs had no effect.
You can see the position in northern China below, and my question for you is: what should the Chinese do? By the way, my opponent (C) believed it would be best for the Allies to try to end the turn by having everyone pass (50% chance then).

EDIT: FYI, we have moved past this point in the game.
