Empire and civilization have no immigrants, houses are not full, and workers are insufficient. What should we do?

Hello, landlord ~ Please send me a screenshot of the specific city-state, or press the following:

1 First, please check the upper limit of houses within the city-state. You can move the mouse over a higher level number to display it immediately. If the house built does not reach the upper limit, it can continue to build houses, which is often ignored by the city owner.

2. Increase the upper limit of residential houses through housing upgrading, thereby increasing the population.

Pay special attention to whether there are houses blocked by tall buildings! ! ! ! ! ! )

Click on the house, and the question mark will describe in detail the reasons why there are no immigrants, such as "people here are still looking for food everywhere", which can be solved by building the corresponding municipal government or shops.

To sum up, "new immigrants are coming"

If workers are badly needed, the landlord should weigh the advantages and disadvantages, demolish the secondary buildings and supplement the main buildings with workers. It is suggested that the secondary agricultural buildings should be demolished immediately to supplement the workers needed by the clinic to eliminate the plague.

Thank you~
