The next big war was when i tried to puppet Japan, China wanted in so it was a good harvest of provinces and subjects from a weak opponent
Again naval invasions to open more fronts against China and thin their big stack
I found out that a good way to advance safely is to mix some generals set on defend front with 1 general with 100 troops 30%+ offence set on attack. That one general will attack but sometimes with more than 100 troops, borrowing some troops from the other generals. Battles in CHina often involved 200+ troops on each side.
