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.
