In Taiwanese temples, it is common to see people lighting incense and making prayers amidst the smoke. They then burn joss paper as a symbol of their offering, completing their prayer. These practices are a part of many belief systems, including veneration of Mazu, which is recognized as intangible cultural heritage by UNESCO. The use of joss paper and incense as a means of communication with the divine is an essential part of the material foundation of these traditional beliefs.
