How to do dry cleaning in winter to make more money?

Winter is the peak season for dry cleaning, and there is a lot of passenger flow. You can make money by doing a good job. If you want to make more money, you can carry out activities such as membership, recharging and issuing coupons, and you can also cooperate with other businesses, such as how much you spend to send laundry vouchers, how much you pay to send laundry members, and how many vouchers you send to supermarkets. I'm afraid you will be too busy after the activity. If the business is too good, you can also open a branch. You can make more money by opening a front shop and a back factory.
