During the Joseon Dynasty, the rituals that were celebrated in the palaces were mainly held inside the palace and in the courtyard of the palace. Mats were spread on the floor of the place where the ritual was held. The mats spread in the Joseon Dynasty rituals divided the space in various ways, and in particular, they were spread in a certain form in the spaces of royal wedding, customs, and court banquet. Mats were the primary physical element that divided the royal ritual space of the Joseon Dynasty, and functioned to elevate the general space to the ritual space. In the ritual space, mats were spread inside the palace, and divided the courtyard of the palace into left and right in a symmetrical form to distinguish the hierarchy of the participants. Mats with special and white patterns were spread in the external ceremonial space and mats with flower and colorful patterns were spread in the internal ceremonial space. This was the subdivision of the Confucianism's male-female division through the mat. The pattern of the mat that divided the space of the royal family elders also meant longevity to reflect the filial thoughts of the Confucianism through the mat. Mats were a physical element for subdividing the royal family and the participants in the hierarchy of the space where the ritual is held, and it also performed a subdividing function between the royal participants. In other words, in the Joseon Dynasty ritual space, mats were temporarily spread while the ritual is being celebrated and functioned to elevate the space to a ritual space. It is confirmed that the fact that the mats were temporarily spread to divide the space into the hierarchies according to the status and were subdivided into colors and patterns to perform the function to reflect the subdivision of the royal family according to Confucianism and the statue of filial piety in the ritual.

The planning acumen led by the crown prince stands out during the banquets that were held continually during the reign of Crown Prince Hyomyung around the late Joseon period from 1827 to 1929. If we examine the changes in banquet space during the period that Crown Prince Hyomyung ruled by proxy, the Jagyeongjeon(慈慶 殿) in Changgyeonggung Palace, which was built during the time of King Jeongjo was repaired after the in 1827 during the reign of the crown prince and appeared in its changed form in Muja Jinjakin 1828. It is believed that the Jagyeongjeonwas expanded and repaired during the reign of Crown Prince Hyomyung to conduct banquets for important guests. Jagyeongjeon which was repaired during the crown prince's reign, is a space where banquets were continuously held during the three years that he reigned, and we can see that it is an important space for royalty where the authority of King Sunjo, Queen Sunwon, and Crown Prince Hyomyung was reflected. Yeongyeongdan(演慶堂) was a structure built in 1828, which is after the period when the Jagyeongjeonwas changed in 1827, and it is a space that emerged during the reign of the crown prince. Hwanchwijeong(環翠亭), which was constructed during the time of King Seongjong was changed after 1827 during the reign of Crown Prince Hyomyung and appeared in its changed form in Muja Jinjakin 1828. Hwanchwijeongwas the place where the Crown Prince Hyomyung stayed and planned banquets and it was repaired along with Jagyeongjeonin 1827. During his reign, the political intent of the crown prince was reflected not in superficial political spaces but in spaces where banquets were held and accordingly the main spaces for banquets and their related royal palace locations were changed or newly established. You need to briefly explain what this and Muja Jinjak are. New information is not provided in this paragraph. You have already established why the crown prince renovated the banquets and its significance in the first two paragraphs. You could just add “Jagyeongjeon(慈慶殿), Yeongyeongdan(演慶堂), and Hwanchwijeong(環翠亭) in Changgyeonggung Palace during his reign were changed and renovated during the time when the royal banquets of the 19th century were getting established. It was spaces that reflected the royal family and royal authority” to the end of the second paragraph and it would convey your intended meaning.

With regard to Gung-jung Yeon-hyang(宮中宴享; court banquet), the frequency of banquets that were held at one time beginning Mu-ja J in-jak(戊子進爵; a royal banquet held in 1828) in 1828 (the 28th year of King Sunjo (純祖)'s reign). In proportion to this frequency, there was an increase in the need and importance of Suk-seol-so(熟設所; a kitchen built in temporarily house for court banquet) and Jung-bae-seol-cheong(中排設廳; a temporary place to put offerings) as a space to assist court banquets. Although Suk-seol-so was a temporary but large-scale facility, it was frequently used for long periods. This facility was flexibly established using the variability of Dong-gung(東宮; Palace for Crown Prince) and enhanced the efficiency of censorship and security in conjunction with palace gates and Suk-wi-cheo(宿衛處; guard station, guard room). In addition, it was reused according to the period when the nation and royal family gave finances or banquets. Jung-bae-seol-cheong was established in the place connected to the central space of court banquets and worked as buffer space to resolve the tension on the day of the event. The location where Jung-bae-seol-cheong was established enabled us to confirm the applicability of Bok-do(複道; corridor) connected to Chimjeon(寢殿; royal residence) when holding court banquets. In short, Suk-seol-so and Jung-bae-seol-cheong were auxiliary spaces, but were considered importantly in the palace operation when holding court banquets.
