Open the qq dazzle dance main interface, click on the game mall, enter the mall, and select the category. There are optional suits, and you can also match your own coat, trousers, skirt, hairstyle, headdress and necessary props. If you like them, you can join the shopping cart and pay directly with coupons. Note that some goods can't be bought with coupons, only Q coins can be used. You can only buy props that don't have the word "coupon receipt" on the picture.
Q coins can be used to buy some rolls, 10q coins = 1050 rolls, which is equivalent to giving you more discounts. If you can't get back the Q coins, the paper will be empty at the end of the month.
