How does the Sims 4 photography studio make money?

The Sims 4 photography studio makes money as follows:

1, choose the right person first, buy a cheap open space, and it is best to make your own home around 1500. After moving in, don't build anything, call yourself to buy a shop, (it is best to choose a place with many people);

Generally, two guests come in. Say hello first, then choose a guest with blue trade value on his head, and leave the rest alone and stare at him all the time;

3, opening a store, with the help of employees can save some effort. If there is a "deal" option, don't shoot it easily. All the customers must have said hello, and both characters are good.
