In the first year, try to harvest as many berries as possible. Arrange at least 2 families for picking, and the first granary can be built right next to it. Have at least 1 person assigned as a warehouse keeper. From March to June, there are a total of 440 normal berries and 880 rich berries. Selling them at the market is a reliable source of initial income.
Selling the 10 tools given at the beginning can bring in a small profit (especially if you choose the 25 gold option to start a line).
Develop sustainable forestry (with at least 3 foresters) for exporting lumber and gears. It’s a low-barrier, reliable source of income. Shields and war bows can also be sold.
Maximize industrial technology points (plate armor can be skipped), and export tools, weapons, and armor (with a focus on rich iron mines; although it takes longer to develop, it becomes very profitable in the mid to late game). It’s not recommended to invest in trade technology; having a strong economy can mitigate the impact of the 10 gold tariff, and focusing on industrial technology leads to faster development.
In the early game, raising sheep in the backyard for exporting leather and shoes yields decent profits, although the price of leather shoes seems to fluctuate more easily.
Import sheep, breed them in moderation, and export wool. It’s a stable investment.
(Limited to fertile green land) Cultivate flax for exporting linen and padded armor. The production efficiency of padded armor is good, and besides meeting domestic needs, it also has certain export value.
