Definition · 定义
Shang Ji (商祭, Shāng Jì) is an ancient Chinese ancestral sacrifice recorded in the Liji (礼记, Book of Rites) in which dried fish (乾鱼, gān yú) served as the principal offering. The name derives from the character 商 (shāng), which carries the meaning of careful measurement, deliberate selection, and considered judgment — qualities that governed the preparation and selection of the fish for ritual use.
Shang Ji belongs to the broader category of food offerings (馈食, kuì shí) in the Zhou ancestral temple system, specifically the subcategory of dried and preserved offerings. Its defining feature is the use of dried rather than fresh fish, a choice that carried both practical and symbolic significance in the Zhou ritual world.

The Significance of Dried Fish · 乾鱼的祭祀意义
The choice of dried fish as the principal offering in Shang Ji was not arbitrary. In the Zhou ritual system, every element of an offering — its type, preparation, and condition — carried symbolic meaning that shaped the rite's efficacy and significance.
Dried fish, unlike fresh fish, resists decay. In the symbolic logic of Zhou ritual, offering food that remained uncorrupted expressed the enduring, incorruptible nature of the ancestral bond. The offering mirrored the relationship it honored: permanent, preserved, and resistant to the passage of time.
The character 商 emphasizes deliberate selection and precise measurement. The fish chosen for Shang Ji had to meet specific quality standards — the right size, the right degree of drying, the right condition. This careful selection was itself a ritual act, expressing the reverence and attention that the ancestral sacrifice demanded.
Dried fish was a widely available preserved food in ancient China, accessible to households across different levels of the social hierarchy. Its use in Shang Ji reflects the Zhou principle that ancestral sacrifice should be within reach of all who owed filial duty to their ancestors, not only the wealthy who could afford fresh meat offerings.
Classical Sources · 文献来源
The primary textual source for Shang Ji is the Liji (礼记, Book of Rites), one of the Five Classics of the Confucian canon. The Liji systematically records the ritual protocols governing every aspect of Zhou social and religious life, including the specific types of food offerings appropriate for different sacrificial occasions.
The authoritative interpretation comes from Zheng Xuan (郑玄, 127–200 CE), whose commentary clarifies both the meaning of the character 商 (careful measurement) and the specific use of dried fish as the offering. Chen Yaoting's (陈耀庭) Encyclopedia of Taoism (道教大辞典) preserves this classical interpretation and situates Shang Ji within the broader history of Chinese food offering traditions. The institutional context within which Shang Ji was performed — the ancestral temple system — is documented in the Zong Miao ancestral temple (宗庙) tradition.
Zhengyi Taoist Connection · 正一道传承
The Shang Ji emphasis on offering quality — careful selection, proper preparation, and the presentation of food that is pure and uncorrupted — did not disappear with the Zhou dynasty. It was absorbed into the Taoist ritual tradition, where it informs the strict standards governing offering items in Zhengyi ceremonies.
In Zhengyi liturgy, the items presented in ritual must be of the highest quality: fresh, clean, properly prepared, and free from any defect or contamination. The priest inspects offerings before the ceremony, rejecting any that fail to meet the required standard. This practice of careful selection directly preserves the 商 principle of Shang Ji — that the quality of the offering reflects the quality of the devotion it expresses. The formal procedures governing Taoist offering standards are documented in the Taoist ritual process, while the historical development of the food offering tradition is traced in the history of Taoist fasting and offering rituals.
