When discussing whether the Jia Xu great movement is the Metal element or the Wood element, we need to deeply understand the Five Elements and Six Qi theory in the "Huangdi Neijing". This article will analyze the climatic characteristics of the Jia Xu year and its corresponding Five Elements attributes based on the records in "Liu Yuan Zheng Ji Da Lun", providing a scientific basis for understanding the Jia Xu great movement.

Climatic Characteristics of the Jia Xu Year

In the Five Elements and Six Qi system, the Jia Xu year has the Lesser Yin Fire governing the sky, the Tai Gong Earth as the central element, and the Yang Ming Metal as the underlying element. This configuration indicates that the climatic features of the Jia Xu year are influenced by the elements of Fire, Earth, and Metal. Specifically, due to the Lesser Yin Fire governing the first half of the year, the climate tends to be hot; during the long summer season, because the Earth element is excessive, there is more humidity and rainfall; and in the second half of the year, due to the Yang Ming Dry Metal governing the undercurrent, the climate tends to be cool and dry. These climatic features correspond to the Fire, Earth, and Metal elements in the Five Elements theory.

Analysis of the Five Elements Attributes of the Jia Xu Year

Based on the climatic characteristics of the Jia Xu year, we can infer its Five Elements attributes. The governing element of the Jia Xu year is Fire, the annual movement is Earth, and the undercurrent element is Metal. Therefore, the Five Elements attributes of the Jia Xu year are mainly Fire, Earth, and Metal. In the theory of mutual generation and control among the Five Elements, Fire generates Earth, and Earth generates Metal, indicating a close relationship between the climatic features of the Jia Xu year and the Metal element.

Medicinal and Dietary Recommendations for the Jia Xu Year

In the Jia Xu year, the selection of medicines and foods should also be adjusted according to the climatic changes. In the first half of the year, when the climate is relatively hot, it is suitable to use salty-cold medicines or foods; during the long summer season, when the humidity is heavy, it is suitable to use bitter-hot medicines or foods to clear heat and dry dampness; in the second half of the year, when the climate is relatively cool and dry, it is suitable to use sour-hot medicines or foods to moisten dryness and counteract coolness. These choices of medicines and foods reflect the characteristics of the Metal element in the Jia Xu year, i.e., the numbers of generation and completion of Metal influence the climate and the corresponding treatment and dietary adjustment in different seasons.

Through the analysis of the climatic characteristics and Five Elements attributes of the Jia Xu year, we can conclude that the Five Elements attributes of the Jia Xu great movement are mainly Metal, while also being influenced by Fire and Earth. The characteristics of the Metal element in the Jia Xu year are reflected in the climatic conditions and medicinal and dietary recommendations, which provide practical guidance for understanding and applying the Five Elements and Six Qi theory.
