This treatise was written to explore the features of Koguryo's World View in the Later Years. The royal titles of the ‘King of Kings’ and the ‘Great King’ were consistently used in the later period, so that it is clear that the king still maintained the minimal authority despite the diminishing royal power.
The expansion of Confucianism and Buddhism also brought about the fundamental changes in Koguryo's social thoughts. Moreover, the introduction of Chinese Taoism to Koguryo in the 7th century further generated the deterioratation of Koguryo's traditional world view values. Also, the Chinese god of Kija was worshipped along with other gods due to this change, which in turn undermined the ritual of the dynasty founder. Such changes symbolized the loss of spiritual center, and one of the factors of Koguryo's downfall.
Another characteristics of later-year Koguryo was the flourishing national construction of cities and fortresses. Koguryo established the ‘three-capitals’ system, which stemmed from the awareness of Koguryo of its own land after it was threatened by external forces. The construction and relocation of the great capital of Jangan were due to the military ventures of Shilla, which pushed its way into the rear regions of Koguryo. However, Koguryo tried to battle this situation by strengthening its base in Pyongyang region, since it had no intention to relocate the capital because of Shilla, which was its former vassal-state. The Great Wall of Koguryo was also built to officially establish the Koguryo's ‘world’ and that of China. Koguryo had made no such attempts before, when Koguryo put itself at the centre of the world. Such movement hence signify that Koguryo was now on the defensive side. Also the Great Wall helped Koguryo to drive out other foreign forces which made an effort to lure some ethnicities within the world of Koguryo.
The advent of Shilla also precipitated the fundamental transformation of Koguryo's policy towards Baekjae. Koguryo made a friendly approach to Baekjae and acknowledged it as the polity beyond the boundaries of Koguryo's influence. However, the old animosity still lingered on, as Koguryo may have pressured Baekjae to acknowledge Koguryo's superiority which Baekjae seemed to have agreed. Meanwhile, Shilla became the direct object of Koguryo's territorial passion. Koguryo's attitude towards Shilla was more of an utter humiliation than wrath, since Koguryo never placed Shilla as its equal. Such mentality was well expressed in the 7th century as well.
Koguryo's attitude towards Malgal and the Japanese Wae was of active nature, contrary to that of Baekjae and Shilla. The name ‘Malgal’ itself was the legacy of Koguryo's world view, as it strived to enhance the control of its rear lands against the foreign pressures on its frontiers. Malgal soon became the ‘Cossacks’ of Koguryo, when it supported Koguryo to fight its Chinese enemies in the 6th and 7th centuries. Simultaneously, Koguryo also made an effort to establish diplomatic relations with Japan. This was due to the fact that Koguryo needed a new ally against the mounting enemies, as well as searching for a new vassal to extend its world view. This proved to be successful but was only restricted to non-military interactions.
