Cultural heritage is a precious treasure left to mankind by history. With the development of the times and the improvement of people’s education, more and more people are becoming aware of the importance of protecting cultural heritage. Chinese porcelain inlay is a type of architectural decoration born out of the specific historical, geographical, and cultural conditions of Fujian and Guangdong, and was included in the second batch of The National List of Intangible Cultural Heritage of China published in 2008 and the third batch of The National List of Intangible Cultural Heritage of China—Expanded Projects in 2011. It represents an important part of the complex traditional culture of Fujian and Guangdong, acting as the essence of national culture, a symbol of national wisdom, and the refinement of national spirit. Using targeted analysis and making changes based on negative reviews, organizations that protect cultural heritage can improve their actions and find new ways to spread cultural heritage. The craft of Chinese porcelain inlay is used as an example in this paper. It combines Python Octopus crawler technology, data analysis, and sentiment analysis methods to perform a cognitive social media visualization analysis of Chinese porcelain inlay, which is a form of national intangible cultural heritage in China. Then, by looking at network text data from social media, it seeks to find out how the Chinese porcelain inlay culture is passed down, what its main traits are, and how people feel about it. Finally, this study summarizes the public’s understanding of inlay porcelain and proposes strategies to promote its future development and dissemination. This study found that (1) as a form of national intangible cultural heritage in China and a unique traditional architectural decoration craft, Chinese porcelain inlay has widely recognized cultural and artistic value. (2) The emotional evaluation of Chinese porcelain inlay is mainly positive (73 and 60.76%), while negative evaluations account for 12.62 and 20.79% of responses, mainly reflected in regret regarding the gradual disappearance of old buildings, the lament that Chinese porcelain inlay is highly regional and difficult to popularize, the regret that the individual has not visited locations with Chinese porcelain inlay, a feeling of helplessness with regard to inconvenient transportation links to these places, and discontent with the prohibitively high prices of Chinese porcelain inlay products. These findings offer valuable guidance for the future dissemination and development of Chinese porcelain inlay as a form of intangible cultural heritage. (3) The LDA topic model is used to divide the perception of Chinese porcelain inlay into nine major themes: arts and crafts, leisure and entertainment, cultural travel, online appreciation, heritage protection, dissemination scope, prayer and blessing, inheritance and innovation, and collection and research. This also provides a reference for the future direction of the inheritance of Chinese porcelain inlay cultural heritage.

Microbial corrosion poses a significant threat to architectural heritage worldwide. This study used metagenomics to investigate microbial diversity and taxonomic groups present in the door walls of the Ji family’s residential houses, as well as their biological functions and chemical cycles. Taxonomic annotation revealed the predominant microbial taxa associated with wall corrosion, shedding light on their potential impact on structural integrity. Moreover, analyzing the metabolites and pathways present in these microbial communities allows for a thorough understanding of their functional capabilities. Our results revealed that areas with significant damage (dwelling bad door (DBD) and dwelling bad wall (DBW)) exhibited a higher microbial diversity compared to undamaged areas (dwelling good door (DGD) and dwelling good wall (DGW)), with variations in the occurrence of archaeal and bacterial species. The presence of bacteria was found to be connected with impaired function in DBW, whereas changes in the community patterns of Sphingobium and Sphingomonas, as well as a decrease in Cercospora proportion and an increase in Fusarium proportion, were correlated with damage in DBD. Both the Entner–Doudoroff (ED) route and sulfide oxidation processes were observed in both damaged locations (DBD and DBW). However, significant nitrogen-cycling mechanisms, including dissimilatory nitrate reduction to ammonium, were only found in DBW. Furthermore, DBD specifically detected the shift from methyl mercaptan (MMPA) to methyl mercaptan (MeSH). This research highlights the intricate interplay between microbial communities and the physical deterioration of residential structures, emphasizing the importance of understanding microbial ecology in mitigating such issues.
