Gyms generally do not return cards or transfer them. After practicing for half a year and two months, I changed places. Someone told me that the half-year card is not refundable, but the annual card is ok.
On the new year's card, you can only transfer the card and deduct 30%. In other words, you have to transfer a 2000 card, deduct 600, and then sell it to others at a low price. In short, you will lose a lot. This is the gymnasium.
There are also some coaches who have no certificates at all, no certificates at all. They just exercise some muscles and wear tights, and they feel great.
A coach said he would take me to practice before, and I couldn't lift chopsticks the next day.
