The far-infrared multifunctional therapeutic device (formerly known as the general therapeutic device) has been on the market for over a decade. Due to its low operating cost (only 1 kWh of electricity is needed for 5 hours of use, with no additional expenses such as changing medicine bags), simple operation, and effective treatment, it has been well-received by a wide range of users. It has now entered hundreds of thousands of households and has been exported to more than a dozen countries and regions abroad. It has also been welcomed by some hospital departments, clinics, and rehabilitation centers.
