Nowadays, dance halls almost always provide public dance mats for practitioners. Practitioners can practice directly. This is a very reassuring thing. But it is difficult to know how many strangers' sweat and dandruff remain on the mat when the same group of trainers lie on the mat with bare hands and feet like you. Is the cleanliness of the dance hall up to standard? Sharing a dance mat with many people is like lying on someone else's land, which is strange and uncomfortable. If you choose a suitable and satisfactory dance mat, it is actually very easy.
