In which period did Beijing Yuanmingyuan flourish?

1723, Yin Zhen acceded to the throne, with the title of Yongzheng. With Yin Zhen's accession to the throne and the arrival of the peaceful and prosperous times of the Qing Dynasty, Yongzheng began to expand the Yuanmingyuan, and built the Hall of Justice and Light, the Hall of Diligence and Grace, and the duty rooms of the Cabinet, the Sixth Department and the Military Department in the south of the Garden, so as to "avoid noise and listen to politics".

The chief designer of Yuanmingyuan is an architect named Lei Jinyu, who was attracted by Kangxi when he was building the Forbidden City. However, in actual construction, most of them are still the views of the emperor, and Kangxi, Yongzheng and Qianlong all personally guided them.

Zheng Da Guangming Hall is the main hall of Yuanmingyuan. It is the place where the emperor holds birthday greetings, banquets of relatives and princes, small banquets of courtiers, banquets of China Yuan Dynasty, dragon dances, Korean War exams, provincial exams and retakes.

Zheng Da Guangming Hall is seven rooms wide and five rooms deep, with corridors, grey tiles and rolling sheds on the top of the mountain. There are five towers in the east and west, namely tea restaurant, imperial study room, tea room and military department. There are also couplets written by Yong Zhengdi and Emperor Qianlong in the temple: Eat and drink in the heavenly heart;

People's happiness is based on harmony.

Find it, there is no future;

Adapt to the times and have a place to live.

There is an imperial book "Zhou Shu Wu Yi" on the east wall, and "Tu Tu" on the west wall. There is Shoushan Mountain behind the temple, and there are bamboo shoots on the mountain, and then moved to Renshou Hall in the Summer Palace.

In the middle of the hall is the emperor's throne, which is made of rosewood and beautifully crafted. The throne is covered with yellow embroidered satin cover. The throne is located on a high platform with three steps below. The platform is surrounded by red lacquered wooden railings, carved with roses and other flowers, which are exquisite and full of charm.

There are high screens on both sides of the throne, which are decorated with aquamarine and peacock feathers, and the feathers of birds are dotted with rubies and jasper. The throne is covered with exquisite embroidered cushions.

Just above the throne hangs a plaque with the word "aboveboard", which is an inkstone plaque with four white characters "aboveboard". As time goes on, white becomes yellow.

The plaque of "Bright Zheng Da" was written by Yongzheng, from Zhu Wengong's Collection of March 8th Answering Zhou Xin in Song Dynasty: If you are aboveboard and have no feud, you will really serve your country.

It means honest, selfless and aboveboard.

Deep patterns are carved on the wooden ceiling, crystal-clear carved glass lamps are hung, and white Korean paper is stuck on the windows. There is also a panoramic view of Yuanmingyuan hanging on the west wall of Zheng Da Guangming Hall, which is so big that it almost covers the whole wall.

On the east wall, there is the book "Yu Zhou Shu No Escape" written by Qianlong Imperial Book. Emperor Qianlong appreciated the layout here and praised: "Without carving or painting, there is a sense of elegance."

Qinxian Hall is located on the east side of Zhengyiguang Hall. The word "diligent and virtuous" comes from the Three Kingdoms period. Zhu Gekongming, the prime minister of Shu, suggested that the emperor should kiss the virtuous, not be a villain, and be diligent in political affairs.

In the middle of the hall is the throne of the emperor to handle government affairs. On the tall screen behind the throne, the calligraphy "Wuyi" written by Yongzheng hangs. Everything comes down in one continuous line, which is intended to encourage yourself.
