There are two ways. The first one: You can directly post a fitness demand, but then the system will recommend your order to a fitness service provider that meets the requirements. You can choose a fitness training that you think is suitable. The second type: first, you choose the appropriate server according to the information of health care service providers displayed on a pp, and then click "About TA". After the other party receives your demand order, you can start the service with Purchase Pass. It's still very simple, I hope to adopt it.
