China’s tourism industry has developed rapidly in recent years, but also promoted the rise of cultural and creative industries. However, due to the immature development of cultural and creative industries and inadequate market supervision, there are many deficiencies in cultural and creative products. At the same time, the quality of Museum souvenirs is uneven, and the utilization rate of resources is low. Given this phenomenon, the author puts forward the method of “PREACH March,” and applies this method and sustainable design theory to the development of creative products in the Terracotta Warriors Museum. Taking the Terra Cotta Warriors and Horses Museum as an example, this paper analyses the defects of the existing souvenirs, refers to the design of the cultural creation products of the Palace Museum, redesigns the souvenirs of its museum sustainably, and solves the problem of how to make the museum souvenirs no longer be placed. “PREACH March” is applied to the design of the museum souvenirs of Terra Cotta Warriors and Horses, and a sustainable and recyclable bookmark is successfully designed. The purpose of this paper is to put forward a practical method for the design of cultural and creative products in the future, and to guide future design to follow the concept of sustainable development.
