${ulcorner}$Hwangje-Naegyeong${lrcorner}$ described Tae Hue(太虛) cosmos which consist of the Great Gi(大氣) produce ${ulcorner}$Hwangje-Naegyeong${lrcorner}$ which affected by the theory of activity of Gi(氣化說) in the Han period represent that Tae Hue is spring head of Gi(氣), concurrently said the Time and the Space were established by operating of Gi(氣). As of the Theories of heavenly structure, ${ulcorner}$Hwangje-Naegyeong${lrcorner}$ was write in long perod, so it include three branch theory. ${ulcorner}$Hwangje-Naegyeong${lrcorner}$ contained the Hypothesis of Covering Heaven(蓋天說), the Hypothesis of Armillary Sphere(渾天說) and the Hypothesis of Chaosheavens(宣夜說) in the Han perod. The Hypothesis of Covering Heaven(蓋天說) means that the sky is round and the ground falls Square(天圓地方). ${ulcorner}$Hwangje-Naegyeong${lrcorner}$ involve the Hypothesis of Covering Heaven by the fact that it divide heaven and earth by top and bottom. The Hypothesis of Armillary Sphere(蓋天說) is not directly appeared in ${ulcorner}$Hwangje-Naegyeong${lrcorner}$. But ${ulcorner}$Hwangje-Naegyeong${lrcorner}$ include the Hypothesis of Armillary Sphere by the astronomical observation and understand the universe with interior-exterior viewpoint. ${ulcorner}$Hwangje-Naegyeong${lrcorner}$ describe the circulation of the universe (周天度數) at 365 1/4 terms, the length of daytime and night of the vernal equinox and the autumnal equinox is same and use the The Twenty Eight Constellations by the ecliptic(黃道). It prove that ${ulcorner}$Hwangje-Naegyeong${lrcorner}$ observes the celestial body according to the Hypothesis of Armillary Sphere. The Hypothesis of Chaosheavens(宣夜說) appears most is the theory which lately. ${ulcorner}$Hwangje-Naegyeong${lrcorner}$ describe Tae Hue(太虛) infinite outer space and the earth is floating by Gi(氣). This with the Hypothesis of Chaosheavens is similar from like this point.
