I worked as a cashier in a gym. General gyms are divided into sub-cards, monthly cards, semi-annual cards and annual cards. The second card is swiped once, and the monthly card is monthly. You can go anywhere within half a year. In fact, if you go for a long time, last year's card is more suitable. If you get a card occasionally, you can swipe it once. If you go alone, the ticket is usually 10 yuan. It is cheaper to get a card.
