Miracle Fitness recently launched a 2-year card, one get one free, only 1600. There is no limit to the number of exercises, no limit to the time, you can stop the card halfway, you can transfer the card, and more importantly, there are gift packages.

Short-term group buying is available online, but it is also more expensive.

But you can buy other people's second-hand cards on websites like "58 City", which is cheaper.
