Due to the rise of modern technology and industry, the handicraft industry inevitably fell into decline, although many of them has been passed on for hundreds of years. Some of them have become intangible cultural heritage but are still on the verge of being lost. In this paper, we separate the population into susceptible person, the exposed, propagandist and silencer to predict potential future of the intangible cultural heritage based on SIR model but with adaptations. Besides, by finding out different disease-free equilibrium under different situations using calculation, hopefully these results could make efforts to protect the traditional culture.
