How come you can dominate the world even though you are still hiding?
Traveling through the late Ming Dynasty, I brought 10,000 acres of fertile farmland - the yield per acre was 4,000 kilograms, and the warehouses were overflowing with grain.
But this was the fourteenth year of Chongzhen. After three years of drought, people ate each other, and millions of refugees passed through the border. Three years later, the Qing army entered the pass. Got food? Where there is grain, there is fat, and everyone wants to take a bite.
So Chen An chose Gou. The yield per mu is not mentioned, the amount of grain is not mentioned, and the ability to keep it is not mentioned. Hide as much as you can, pretend to be as poor as you can. Recruiting and training troops in secret, pretending to be poor and farming in the open. Every time I'm forced into a corner, I reveal my hand - and then continue to hide it.
