Switch the tributary demand depending on which idea group you are working on. Late game, you can use client states to form vassal shield which is a bit more convenient. Ideally, this vassal will have cores in the big nations so you don’t have to wait for claims and just use the reconquest cb. Once you start getting close to the big nations such as Ottomans and Russia or Muscovy, you should plan ahead on what provinces you conquer so you can either release a vassal or vassalize an existing nation. As Ming, if you border a non tributary nation, you lose mandate. Make sure you bring enough units or just wait till the rebels starting sieging your fort. That means you will suffer a lot of losses. When fighting rebels early game, remember you will be attacking in mountains most of the time.
Yes it affects meritocracy but In about 100 years or so, your meritocracy will remain high enough. You should almost always take +harmonizing progress from events. Once I get the extra diplomat from Celestial reforms, I put one on automatic to improve relations with subjects. Either improve relations with prospective tributaries or current tributaries.
And Declare on either Korchin or Haixi as soon as possible. For the ones who can’t give you monarch points, get manpower for starting few years. Set all tributaries to give you admin. Get the decree for infant combat ability. That’s the way we are going to start our conquests. Exceptions are your neighbors to the north (Korchin, Haixi, Jiangzhou, Buryatia, Yeren, Oirat, Chagatai). Start establishing tributaries to whoever would accept. Improve relations/diplo rep for diplo and Morale/discipline for mil. Get level 2 advisors from the start, you can afford it. So if you try a little hard and pay close attention, you can do a world conquest fairly easily. The only nations that were not my tributary were France, Austria and Great Britain. In my last play through, I was purposely playing very passive and I still manage to take all of Asia, Indonesia, East Europe, Arabia and Africa. You can play Ming very casually and still manage to own more than half of the world between you and your tributaries. Ottomans might be the best nation to do world conquest, but I think Ming is actually the easiest one for beginners. Ming starts in isolation as THE biggest nation in the world, number one great power and you are going to remain there for rest of the game even if you don’t play super aggressive. Half way through my last Ming game I realized that Ming really doesn’t need a play by play rule book. I was planning on a step-by-step guide on how to world conquest playing Ming.
