1. Rouge Shop

①Buy all six ordinary tables first, and then upgrade the tables, so that customers will not queue for a long time;

②The price of the product will be reduced after two hours, so don’t spend your money after buying the ordinary table. Be sure to buy high-priced products first.

③ Double income is best used when the value of the product is the highest within two hours.

④Save 100 beads. Don’t recruit them all. You need to upgrade the store later, so you must save beads;

2. Shenyan Store

①Upgrade the facilities first when they can be upgraded, and then continue training after reaching level three.

② I often go to Shenyan Shop, and the gossip spreads much faster than the teahouse.

③Don’t use the five invitations on the first day. Wait until you participate in the store’s secondary selection before using the invitations. You can complete the selection one day in advance.

④The biggest pitfall is that the value will be fixed after members of the selection committee submit it, so click on it and you’ll get it! Don't send it in as soon as you draw it.

3. The best way to supplement double income is: don’t use double income first, wait until the recruitment reaches 30, then open double income, and then go to attract customers;

That's all I can think of at the moment. Shopkeepers are welcome to add more.
