Core Viewpoint - The article emphasizes the significance of traditional Chinese craftsmanship, particularly the mortise and tenon joint technique, which has been a cornerstone of Chinese architecture for thousands of years, showcasing its cultural heritage and modern applications [1][18]. Group 1: Historical Significance - The mortise and tenon joint technique, known as "榫卯," has been integral to Chinese architecture from the Neolithic era to the Ming and Qing dynasties, reflecting a rich architectural history [1][3]. - The technique was recognized as a UNESCO intangible cultural heritage in 2009, highlighting its importance in preserving cultural identity [1]. Group 2: Architectural Mastery - The article describes the structural components of the dougong (斗拱), which is a pinnacle of the mortise and tenon technique, providing stability and resilience to buildings [7][10]. - The Yungang Wooden Pagoda, with its 54 combinations of dougong, serves as a "dougong museum," demonstrating the technique's effectiveness in earthquake resistance [12]. Group 3: Modern Applications - The mortise and tenon technique has found new relevance in modern engineering, such as in the design of aircraft engines, where it helps distribute centrifugal forces [18]. - Innovative applications of the technique are being explored in China's lunar program, proposing the use of mortise and tenon structures for building a moon base [20]. Group 4: Cultural Transmission - Individuals like "Dougong Grandpa" and Liu Wenhui are actively promoting traditional craftsmanship to younger generations through engaging educational methods, such as hands-on workshops and interactive models [14][16]. - The development of mortise and tenon building blocks aims to simplify and popularize traditional techniques, making them accessible to a broader audience [16].
