	=== Identification of stars ===		=== Identification of stars ===
			Before the transmission of European astronomy to China, the identification of the three stars of '''Neichu and Jiu''' remained generally stable. During the astronomical reforms of the late Ming period, however, the whole asterism Neichu and one star of Jiu appears to have been omitted, possibly because its constituent stars were difficult to identify. When Jesuit astronomers compiled new star catalogues in the Qing dynasty, they attempted to restore the traditional Chinese asterism system; nevertheless, their identification of the stars of Neichu differed from that followed before the late Ming reforms.

	Chinese ~~constellation~~.		Nèichǔ (“Inner Pestle”) is a three-star Chinese asterism belonging to the Gan school, represented in black in the three-school tradition. It lies in the region assigned to the lodge Wēi (危), close to Rén (人, “People”) and Jiù (臼, “Mortar”). Under modern IAU boundaries, its members fall in Pegasus and Lacerta.

	...		A '''chu''' (Pestle杵) was a rod-shaped implement used for pounding grain, normally in combination with a mortar (''jiu'' 臼). Together, the pestle and mortar formed one of the most basic devices for processing foodstuffs. They could be used to dehusk grain, pound rice, produce flour, and prepare ritual food; implements of similar form were also employed for grinding medicinal ingredients or working other materials. The ''Xici II'' commentary of the ''Book of Changes'' states: “…cut wood to make pestles and dug the earth to make mortars; through the benefit of mortar and pestle, the myriad people were sustained斷木為杵，掘地為臼；臼杵之利，萬民以濟.” Early mortars could be made by hollowing depressions directly into the ground or into blocks of stone, while pestles were fashioned from short pieces of wood or elongated stones. Archaeological evidence indicates that the invention of the pestle and mortar reaches far back into prehistory. Stone pestles have been excavated at both the Baozitou site in Nanning and the Zengpiyan site in Guilin, which date to approximately 10,000–9,000 years ago.

			The prefix '''nei''' (Inner内) does not indicate that the implement was kept indoors. Rather, it served as a distinguishing element within the nomenclature of Chinese asterisms. Yang Boshun has argued that the Gan school deliberately coined some of its asterism names with reference to names already used in the Shi-school system. Since the Shi school already had an asterism called '''Chu''' 杵, the Gan school designated another one as '''Neichu''' (Inner Pestle内杵), “Inner Pestle.” Comparable pairs include '''Tianjie (Celestial Steps'''天阶)'''–Neijie (Inner Steps'''内阶) and '''Ping (Screen'''屏)'''–Waiping''' ('''Outter'''外屏). The name Neichu therefore served primarily to distinguish this asterism from another Chu belonging to the Shi-school tradition and located south of the lunar lodge Ji 箕.

			Sun Xiaochun and Jacob Kistemaker treated Neichu, '''Jiu''' 臼, and the nearby '''Tianchu''' 天厨 as a coherent group within the same sector of the sky. They connected these asterisms with the ancestral-temple imagery associated with the neighboring lodges Shi 室 and Bi 壁, interpreting them as cooking and food-processing facilities used to prepare special offerings for ancestral rites. This interpretation emphasizes the idea of a ritual kitchen. Other sources, however, including the ''Kaiyuan zhanjing'', the ''Xingjing'', and the astronomical treatise of the ''History of the Song'', preserve prognostications concerning the “annual harvest” and “military provisions.” In this context, the pestle and mortar symbolized the harvesting, storage, and processing of grain, especially supplies intended for the army. Although these interpretations may derive from different intellectual and astrological contexts, they share the same central semantic field: the harvesting, storage, and processing of food grains.
