Changdeok Palace was built in the 3rd year of Yongle in the Korean dynasty (1405, 5th year of Taizong in the Korean dynasty), and is located at the eastern foot of Beiyue Mountain in Seoul, the capital of the Korean dynasty (now Seoul, South Korea). It was built as an independent building outside Gyeongbokgung Palace and is called Dongque. Changdeok Palace is the second palace built by the Korean dynasty after the construction of Gyeongbokgung Palace in the 28th year of Hongwu (1395, the 4th year of Taizu, Korea). When Emperor Taizong of North Korea ascended the throne, the capital of North Korea had moved from Seoul (now Seoul, South Korea) to Kaesong. By October of the second year of Yongle (1404), Emperor Taizong still took Seoul as the capital and ordered the construction of a new detached palace. By October of the following year (1405), the palace was completed and named "Changde Palace". Later generations explained that its name is "Chang Ye, the virtuous person is also virtuous, and the Tao is also sacred. If there is holiness and then there is Taoism, there must be virtue and then it can flourish", so the name of Changde Palace means "inspiring people to prosper". When Changde Palace was built, there were buildings such as main hall, newspaper hall, toilet hall and main bedroom hall. In the ninth year of Yongle (141year, the eleventh year of Emperor Taizong), pavilions, sleeping halls and stone bridges were added, and the yamen was discussed. In the tenth year of Yongle (14 12, in the twelfth year of Taizong), Dunhua Gate was built and various departments were set up. In the sixteenth year of Yongle (14 18, the eighteenth year of Taizong), the Qichao Hall was built, and the main hall of Changde Palace was moved to its current site, with three rooms wide and expanded to five rooms wide. In the seventeenth year of Yongle (14 19, the first year of Sejong in Korea), the southward corridor of Ren Zhengdian was built. In the fifth year of Tianshun (146 1 year, the seventh year of Sai-jo in Korea), the halls and pavilions in Changde Palace were named, and the palace walls were greatly expanded in the seventh year of Tianshun (1463, the ninth year of Sai-jo). The main palace gate was named in the 11th year of Chenghua (1475, the 6th year of Emperor Chengzong).

In the early period of the Korean dynasty, the king mainly used Gyeongbokgung Palace, but seldom used Changdeok Palace. Li Chenggui, the great ancestor of Korea, died in Changdeok Palace. After Emperor Chengzong and Yan Shanjun came to North Korea, the use of Changdeok Palace became frequent. In the 20th year of Wanli (1592, the 25th year of Xuanzu, Korea), the Japanese army invaded Korea on a large scale, and the Chingde Palace, Chang Gung Palace and the main palace, Gyeongbokgung Palace, were all burned down. Later, with the assistance of the Korean and Ming armies, the Japanese rebellion in Nanjing was put down. After Xuanzu of North Korea returned to Seoul, he did not rebuild Gyeongbokgung Palace or Chindeok Palace, but used Yueshan Dajunfu as a temporary palace, called Qingyun Palace (now Deshou Palace). After Guang Haijun ascended the throne, the reconstruction of Quegong was still put on the agenda. Due to the large scale of Gyeongbokgung Palace (782 palaces) and limited financial resources, priority is given to rebuilding the smaller Qingde Palace (238 palaces). In the thirty-seventh year of Wanli (1609, the first year of Guang Navy), Guang Navy rebuilt Changde Palace. But this new palace was burned down in Renzu anyway. In the fourth year of Shunzhi (1647, and the twenty-fifth year of Renzu), Changde Palace was rebuilt again. As a result, the Renqing Palace built by Guang Navy for Princess Renmu at the foot of Wangren Mountain was demolished, and most of the halls were demolished to build Changde Palace.

According to the Governor's Ceremony of Repairing Changde Palace, when Renzu Dynasty rebuilt Changde Palace, it moved Zhengguang Hall of Renqing Palace into Zhengxuan Hall of Changde Palace, Qingshou Hall and Zhenghong Hall of Renqing Palace into Dazao Hall of Changde Palace, and Zhengqian Hall into Zhengqian Hall. In addition, Qingji Temple in Renqing Palace moved to Baoqing Temple, Qingwa Temple moved to Tongming Hall, Wuyi Hall moved to Yanghe Hall, Qingyun Hall moved to Yanxi Hall, Xian Zhen Hall moved to Yanqing Hall, Shoulv Hall and the edge moved to Jingchun Hall, Shoushou Hall moved to Hanren Pavilion, Zhengshun Hall moved to Chengguang Building, Rende Hall moved to Taihe Hall, and Qingning Hall moved to. Demolition of the Red Gate South Moon Gallery and construction of Ren Zhengtang East Moon Gallery. In addition, other halls and porches of Renqing Palace were demolished, and buildings such as Chucheng Hall (the East Palace of the Prince, which was burnt down during the Yingzu period, was not rebuilt), Yuhua Hall, Ranjing Hall, cooking stove, candle room and Biejian Hall were built. In the forty-sixth year of Wanli (16 18, ten years of Guanghai), the main palace of the Korean dynasty was moved from Qingyun Palace to Cheong Tak Palace. In the next 250 years, the Chingde Palace replaced the Gyeongbokgung Palace and has been used as the main palace in North Korea. During the Renzu period, Zhao Guiren, a harem in collusion with the Golden Palace of the powerful minister, once buried the bones and trees of children dug out of the cemetery in Changde Palace and Changqing Palace, cursing Wang Shizi's filial son Li Hao and empress Zhuang Lie, so that his son could ascend to the throne. Therefore, after Emperor Xiaozong of North Korea ascended the throne, he carried out renovation works on Changdeok Palace and Changgyeonggung Palace, and removed the temperature bulges (underground kang) in all the halls of the two palaces, re-changed the soil and re-paved the temple bricks. The project started on February 16, the ninth year of Shunzhi (1652, the third year of filial piety in Korea) and ended on March 25th. Due to insufficient budget, 2,000 monks were recruited and assigned to Renqing Palace and Guandi Temple to participate in the clean-up project. Due to the continuous excavation of vicious and filthy underground things, North Korea's filial piety did not return to the palace here long after the project ended, but lived in Qingyun Palace.

In order to support Cixi big princess, in the 11th year of Shunzhi (1654, the fifth year of Xiaozong), the temple of guarding the scriptures in Changde Palace was renovated, and the buildings of Qinjing Pavilion, Zhengqi Pavilion, Pixian Pavilion, Guanwen Pavilion, Xiehe Building, Chenghui Building, Yuzao Hall and Vientiane Building in Qingde Palace (now Qingxi Palace) were demolished. In the 43rd year of Kangxi (1704, the 30th year of Susong, Korea), a large newspaper altar was built in the back garden of Changde Palace to worship Ming Di. When North Korea was founded, the Zhang Kui Pavilion was built in Zhouhe Building in the back garden of Changdeok Palace, which was a famous royal library.

On the evening of the eighth year of Jiaqing (1803, the third year of Chunzu in North Korea)1February 13, a fire broke out in the westbound corridor of Zhengxuan Hall, the convenience hall of Changdeok Palace, which was used to handle daily affairs. The fire spread to Zhengxuan Hall and Renzheng Hall, the main hall of Changdeok Palace, threatening Xuanyuan Hall, the west of Renzheng Hall, where ancient kings were dedicated to earthquakes. The fire dealt a great blow to the king's Queen princess royal King, who stopped listening to politics for fifteen days after the fire. In the ninth year of Jiaqing (1804, the fourth year of Chunzu), Ren Zhengtang was rebuilt in August and completed four months later. In the 25th year of Jiaqing (1820, 20th year of Chunzu), the map of Dongque was drawn, which became the only image data that comprehensively described the ancient palace in Changde.

In the 9th year of Daoguang (1829, 29th year of Chunzu), at noon on August 1st, a fire broke out in Chang Gung Palace during the funeral for Prince Xiaoming. When raising funds for the reconstruction of Changjing Palace, a fire broke out in Changde Palace on October 17th in the tenth year of Daoguang (1830, thirty-three years of Chunzu). The fire started in the Sleeping Hall building and spread to Xizhengtang, Chengguang Building, Jing Xun Pavilion, Yuhua Hall, Yangxin Pavilion, Longqingxuan, Xingfu Pavilion, Qizheng Pavilion, Silent Hall, Kesuizhai, Qing Xiang Pavilion, Jixiang Gate, Sightseeing Hall, Burning Stove and Hangge Gate. This is the biggest fire in the Korean Palace after the Japanese rebellion in Nonchen, and all the inner palace areas were reduced to ashes. At this time, Chunzu lived in Qingxi Palace, so Changde Palace was idle. As the Cheong Tak Palace was the only large palace in North Korea at that time and was used as the main palace, the reconstruction work began on the first 10 day after the fire. First of all, the Dazao Hall, Zhengqian Hall and Chengguang Building (the lower floor is Jing Xun Pavilion) where Ming Shenzong's gifts were preserved were restored. The following year, Xingfuxuan, Longqingxuan, Yuhua Hall, Yangxin Pavilion, Zhengqi Pavilion, Silent Hall, Kesuizhai, Qing Xiang Pavilion, Jixiang Gate, Xuanping Gate, Xieyang Gate, Yaohui Gate and Tongchun Gate were restored. There are 2,000 logs, 3,000 logs and 2,000 columns in the restoration project, all collected from Jincheng, Ningyue, Langchuan and Lindi in gangwon. In order to prepare wood, a mountain closure order was issued, and it was forbidden to enter the mountain. In September of the 14th year of Daoguang (1834, the 4th year of Chunzu), the reconstruction of Changde Palace was finally completed. In April of the fourth year of Tongzhi (1865, the second year of Emperor Gaozong of Korea), Regent Xing Xuan da Yuan Jun decided to rebuild the Gyeongbokgung Palace. In November, the sixth year of Tongzhi (1867, the fourth year of Emperor Gaozong), the Jingfu Palace was completed, and in July of the following year (1868), the royal family officially moved into Jingfu Palace. However, there were also twists and turns during the period. In the 13th year of Tongzhi (1874, 11th year of Emperor Gaozong), the royal family moved to Changde Palace again because of the explosion in Gyeongbokgung Palace. In the eighth year of Guangxu (1882, the nineteenth year of Emperor Gaozong), in June, due to the ominous sign of "the horse entered the palace" in Changde Palace, Emperor Gaozong decided to move back to Jingfu Palace. However, due to the outbreak of "Renwu mutiny", he stopped moving and continued to live in Changde Palace. In the 10th year of Guangxu (1884, the 21st year of Emperor Gaozong), the "Shen Jia coup" broke out, and Changde Palace became the battlefield of the Qing army and the Japanese army, which was destroyed, so the royal family moved to Jingfu Palace in the first month of the following year (1885). After more than 20 years, Changde Palace was almost deserted and overgrown with weeds. In the first year of Longxi (1907), Li Di, the pure ancestor of the Korean Empire, and Yin Shi, the queen of pure filial piety, and Li Yin, the crown prince, moved from Qingyun Palace (Deshou Palace) to Changde Palace. Since then, Changdeok Palace has become the residence of the last royal family of the Korean dynasty. In the fourth year of Longxi (19 10), the last command meeting of the Korean Empire was held in Xingfuxuan, Changdeok Palace, and the meeting decided to merge Japan and South Korea. With the signing of the Japan-South Korea Merger Treaty, the Korean Empire and the Korean Dynasty, which lasted for 500 years, perished, and the Korean Chunzong continued to live in Changdeok Palace, known as the "King Lee of Changdeok Palace". In the sixth year of Dazheng (19 17, the tenth year of Chunzong), another fire broke out in Changde Palace, and then the Dazao Hall and Zhengqian Hall were rebuilt, but they were not repaired, but with a strong Japanese style. After the death of Chunzong, Yin Shi, the filial piety queen of Chunzhen, and Yi Bangjia, the wife of Li Yin, lived in Leshan Hall of Changde Palace until 1989.

After 1954, Changdeok Palace was nationalized by the government of the Republic of Korea and gradually opened to the public. 1963 was designated as the historical site number 122, in which Ren Zhengdian in Changdeok Palace was listed as the national treasure of the Republic of Korea. During the period of 1997, at the UNESCO World Heritage Committee held in Naples, Italy, Changde Palace and Shui Yuan Huacheng Post were included in the world cultural heritage. When Changde Palace was rebuilt, it was based on its original appearance, so it still maintained its original style, with 3 buildings/kloc-0 and 28 pavilions. Changdeok Palace has many historical and architectural values, and the Korean drama Dae Jang Geum was also shot in the lotus pond in the palace. Because it belongs to the world cultural heritage, the cultural heritage tour guide system is implemented, and tourists can only visit the palace if they visit the established tour guide group. There is a free tour system every Thursday. Visitors can visit the palace by themselves, but the admission fee is more expensive. It is better to join a guided tour group.
