Your problem is still planning. I suggest that you don't have to go through every level to meet the requirements. Try to earn more money. You can make money every year. There are some valuables and weapons in the warehouse.
Land planning is reasonable. Leave room.
Because of this game, from the mid-term, there will often be a certain level to continue building the city you built before. If you don't lay a good foundation at this time, you will be in trouble. If you have more money, you can start all over again and waste some time. It would have been sad if I had robbed Peter to pay Paul last time. Seriously, you may never play again.
As for the problem you mentioned, it is not difficult to solve it. Tear down the miracle and improve the level of the house, because the highest level of the house you closed here is definitely higher than last time, and it can accommodate more people, as long as you meet the needs of the residents.
Now is to improve the efficiency of residential areas. There are many good ways. You can search the layout of Dragon and Tiger Leaps on the Internet.
If you really can't find it, you can leave your email and I'll send you my screenshot.
