Consider moving all the 5th Chinese Corps Divisions (six), all 6th Chinese Corps Divisions (three), and the 3rd New Chinese Corps (a long walk-rail-walk from near Nanchang) across the Burma border, then retreating them to India as the Japanese push into northern Burma.
Once the Burma Road is cut there will not be enough supply to fully support ground and air operations in China, and the dozens of under strength divisions and corps will stay that way. Conversely, any Chinese corps in India can grow fat on Indian supply, and expand into an impressive combat force.
Whether or not this is practical depends on your house rules about the need to spend PP to release restricted units to cross borders. If you have to pay 'retail' (full cost) then don't bother; the allies have other pressing needs for PP in the first few months of the war.
