Actually the Communist China setup at the start is right on the money and only includes the three provinces they always had in vanilla. The reason it shows 4 in your map is that your shot is taken in March, not Jan 1, 1936. It is normal for the Commies to pluck off a province or so, until the Xian incident fires. Definitely Shanxi, not Japan should have Xining and Huahaote. I'd say give the 6 far southeastern provinces of Shanxi to Nationalist China, give the 3 provinces to Yunnan indicated (Sichuan warlords were not 100% under control yet - only became fully under Nationalist China jurisdiction when Liu Xiang sacrificed his life to the Japanese) and the one Nationalist China province you indicated should be changed from Nationalist China to Xibei San Ma. Xinjiang should be IMO left alone. Xinjiang was indeed contested until about April 1937 but should stay as is until the event support is written.
The rest of Shanxi is something I'd like to have more debate on before changing. The Japanese should normally be able to chew their way through the northern region and keeping it as Shanxi is a good way to accomplish this.
Whatever we do I'd like this to still be possible:

Hadn't noticed the date. On maps of the Long March, I don't think I've seen the communists occupying much of Gansu, which the third province is. It's usually just the north of Shaanxi, which judging by the screenshot is just those two provinces I mentioned. Then again it's not close up so I'll refrain from comment on specific provinces. As I said before I'd simulate Shanxi's inaction to take down Com China by having them at peace. Perhaps even give Shanxi, Xian to encapulate CHC. The Xian was in Xian because Chiang flew there to investigate why Shanxi wasn't taking care of Com China. Perhaps have more event. If Shanxi doesn't declare war, a decision has Chiang flying to Xian. There he can choose between side with the commies or to bully Shanxi in declaring war. Then Shanxi gets the event to be bullied or kidnap Chiang.
I'll agree with Shanxi getting Northern China for the time being. Since there's no Shandong warlord (as a country), to funnel the Japanese towards Nat China.
Sichuan could be handled by event. It's just that I'd keep Chonqing as Nationalist, as most events are built around Chonqing as a second capital. Don't want to risk the events not working due to one event not firing.
