How does Julius Caesar 3 keep the residents' supplies from decreasing?

In order to make the city prosperous, we must constantly improve the housing conditions of residents.

So at the beginning of the game, we should plan reasonably. Residents' houses should not be too close to workshops, military camps, barns and warehouses, otherwise the living conditions will be difficult to improve. The construction of residents' houses depends on quality, not quantity. Therefore, we should leave enough space to build wells, gardens, fountains, barbershops, bathhouses, schools, libraries, temples and so on. Build more reservoirs and aqueducts, so that the housing conditions of residents will be improved soon.

From a small tent, pass by a big tent, a small shed, a big shed, a small shed, a small house, a big house, a small building, a middle building and a big building. Of course, many immigrants will move in to reach the population needed for the game to pass.

The upgrade of the house comes at a price, and it needs a lot of furniture, pottery, wine and marble to decorate it. There are gardens, squares and fountains nearby, and it is close to hospitals, bathhouses, schools and theaters. Therefore, this is also the embodiment of the city's comprehensive strength.
