Core Viewpoint - The protection of intangible cultural heritage (ICH), especially lesser-known forms, is essential for preserving the roots of Chinese civilization and cultural diversity, as they carry unique historical memories and potential for modern industry [1][2]. Group 1: Importance of Lesser-Known ICH - Lesser-known ICH projects, despite being less recognized, play a crucial role in documenting historical production levels and social structures, embodying collective wisdom [1]. - An example is the Naxi Dongba paper-making technique from Yunnan, which preserves the original form of Tang Dynasty paper-making and serves as a "living fossil" for studying ancient techniques [1]. - Protecting lesser-known ICH allows for a connection between ancient and modern cultures, as seen in the evolution of traditional festivals like the Dragon Boat Festival [1]. Group 2: Economic and Cultural Impact - Lesser-known ICH serves as an "invisible engine" for industrial innovation, with over 12,900 ICH workshops contributing to local economies through unique product development [2]. - The integration of traditional techniques with modern design, such as Miao wax dyeing in fashion and Dong ethnic songs in animation, demonstrates the potential for economic revitalization [2]. - Lesser-known ICH is vital for cultural integrity and diversity, exemplified by the Luban lock as a symbol of peace and the Xinjiang paper-making technique as a means of cultural connection for overseas Chinese [2]. Group 3: Creative Transformation and Innovation - The "14th Five-Year Plan" emphasizes the need for systematic protection and innovative development of ICH, particularly focusing on the survival challenges of lesser-known forms [3]. - Innovative practices, such as transforming oil paper umbrellas into creative lampshades, highlight the potential for ICH to inspire solutions to modern problems [3]. - The growing interest in cultural heritage and creative industries reflects a cultural awareness and resource availability that supports the revival of lesser-known ICH [3]. Group 4: Cultural Identity and Future - Protecting lesser-known ICH addresses the cultural question of "who we are," showcasing the continuity of cultural genes and the confidence of an ancient civilization facing the future [4]. - An open-minded and innovative approach is necessary to ensure that every cultural gene finds its stage, allowing Chinese civilization to thrive [4].
