TopIn the 1980s, a new concept, sustainable development, was put forward, which means that meeting the material and spiritual needs of contemporary people will not damage the ability of future generations to meet the same needs (Yan & Feng, 2014; Niinimäki & Koskinen, 2011; Sherwin, 2004; Turner, 2009). In easy-to-understand terms, it means that “you can't eat your ancestors' meals and cut off your children's food” (Klocke & Lein, 2020; Guo, 2021). Intangible cultural heritage is the realistic embodiment of tradition in contemporary life, and it is constantly endowed with the wisdom and creativity of the people (De Eyto et al., 2008; Cucuzzella, 2016). This can also be reflected in the data of nongenetic sowing vitality values of cities in China, as shown in Table 1 below. In addition, sustainable development has three important meanings: (a) It is conducive to promoting the unity of ecological, economic, and social benefits (Skerlos et al., 2006); (b) it is conducive to promoting the transformation of economic growth and achieving the goal of economic development in harmony with population and environment (Shi & Chew, 2012; Tang et al., 2016); and it is conducive to the sustained, steady, sound, and upward development of the social economy and improves the quality of people's happy life (Esswein et al., 2011). To sum up, China's intangible cultural heritage needs to take a road of sustainable development (Duke et al., 2018).
