Abstract
Using the design method proposed by Kunii, this study mathematically explains the achievement of Kublai of merging two different societies to build a globalized nation after conquering China. The considered design method, called incrementally modular abstraction hierarchy, consists of seven levels, from the most abstract, homotopy, to the most concrete, computer graphics. Moreover, it allows a flexible design while moving up and down its hierarchy. Using this method, we attempt to restore the concepts of Kublai, aiming to build a globalized state by combining nomadic and agricultural cultures. Specifically, we examine the use of two capitals to resolve the problem of different lifestyles of the Mongolian Khan, who moved between the summer and winter camps of the nomads, and the Chinese Emperor, who lived in a fixed palace of the agricultural people. By incorporating the category theory into Kunii’s method, we discuss the adjunction of the Mongolian 1000-household social and military system based on decimal numbers with the Chinese bureaucratic system. The inclusion of the category theory in his original method allows visualization by programming, making the design more versatile and flexible.

Definition of an attaching space. Let there be two topological spaces X and Y, and let Y be adjoined to X to obtain an attaching space \({Y}_{f}$$.\, {\text{Thus}},$${Y}_{f}=Y{\bigsqcup }_{f}X=Y\bigsqcup X/\sim \) is the space attaching Y to X with an attaching function f, where \(\bigsqcup \) denotes a disjoint union.
The Central Secretariat was the policy-formulating agency. The Department of State Affairs managed the six ministries and was the highest executive institution. The Chancellery advised the Emperor and the Central Secretariat. Each department had a minister or secretary with two assisting vice-ministers or secretaries. The Ministry of Personnel was responsible for the appointments, promotions, and demotions of civil officials. The Ministry of Revenue was in control of collecting census data, collecting taxes, and handling state revenues. The Ministry of Rites commanded state ceremonies and rituals. The Ministry of War had the responsibility for the appointments, promotions, and demotions of military officials. The Ministry of Justice ruled judicial and penal processes. The Ministry of Works managed governance construction projects, hired artisans and laborers, and manufactured governance equipment.
