How to train businessmen in civilization 7
Before you set up a trade route, you first need a producer. Merchants are key figures in establishing trade routes between different settlements. To unlock businessmen, you need to study relevant technology nodes in the technology tree.
In ancient times, you needed to study "legal code", which required you to study "mysticism" and "discipline". After completing these studies, you will see merchants in the Production tab of any city, town or capital. After producing a merchant, you will get a merchant unit.
When you enter a different era, you may find that you can no longer produce merchants. This is because the merchant is once again locked behind another node in the citizen tree, just like the "legal code" in ancient times. For example, in the age of exploration, you need to unlock "economics" citizens. In the modern era, you need to unlock the "steam engine" in the tech tree.
Losing the ability to build a trade route is really frustrating, but it is part of the game for the moment.
