This project is to map the national-level protected buildings with help of the Shaanxi Provincial Cultural Heritage Administration. Our team is answerable for mapping the Zunjing Library of Confucius temple in Heyang. Confucius Temples, also called Wen Temple, are built to commemorate the great Chinese thinker and educator Confucius. In ancient China, they were located in all places in China. Among the buildings within the complex, Zunjing Library is a place for classics, which has always been the holy temple for refined scholars. Zunjing Library is a three-floor ancient building with an East Asian hip-and-gable roof. In addition to the mapping of this architecture, we should also complete a series of e-technical drawings, including its detailed data, various plans, elevations, sections, and node diagrams.
