	The modern identification of the six stars of Nandou is relatively stable: ζ, τ, σ, φ, μ, and λ Sagittarii. Historical catalogues describe the internal form as a bowl (kui) and a handle (bing or biao). The determinative star is the fourth star of the bowl, φ Sagittarii; while Tang astronomer Yixing also mentioned that in Han dynasty the first star of the bowl was used as determinative star. Because the direction of numbering differs among catalogues, the table below is arranged by traditional asterism position, with Yi Shitong's common numbering indicated in parentheses.

	In official astrological literature Nandou was not merely a vessel-shaped figure. Its member stars were interpreted as a Celestial Temple, Heavenly Storehouse, Heavenly Treasury, celestial gate, imperial banner, and administrative pivot. The material image of a dipper was therefore reinterpretated as a wider symbolic system of imperial administration. This asterism was also regarded by some people as governing ranks, emoluments, lifespan, and military affairs.		In official astrological literature Nandou was not merely a vessel-shaped figure.
