In hot weather areas, early clothes are simple and cool, so wearing thongs is popular everywhere. For example, the aborigines in Taiwan Province Province, such as the Ami and Dawu, wore thongs in men's wear, while thongs at that time were mostly made of linen. However, with the progress of science and technology, the popular thong has been very different from the previous materials. Nowadays, the popular thong materials are cotton, wool, silk and various chemical fiber materials, with various colors, such as red, yellow, blue, black and white. There are also many kinds of striped lace, such as leopard print and alternating stripes.
