1. Basic Location & Historical Evolution
The Hall of Central Harmony sits exactly on the central axis of the Forbidden City, sandwiched between the Hall of Supreme Harmony in the south and the Hall of Preserving Harmony in the north. Together with the other two halls, they form the Three Grand Halls of the Outer Court, the core ritual zone of the imperial palace.
Built in 1420 (the 18th year of Yongle reign, Ming Dynasty), its original name was Huagai Hall (Canopy Hall).
Rebuilt after a fire in the Jiajing period and renamed Zhongji Hall.
In 1645 (the 2nd year of Shunzhi reign of the Qing Dynasty), it was officially titled Hall of Central Harmony. The name derives from The Doctrine of the Mean, meaning maintaining impartiality and harmony to stabilize the whole nation携程.
Multiple renovations were carried out in the Ming and Qing dynasties, and the existing building retains the architectural style of the Ming Dynasty.
2. Architectural Parameters & Unique Structure
It is the smallest building among the three grand halls, with obvious architectural characteristics different from Taihedian:
Overall size: Square plane, 24.15 meters on each side, total construction area 580 ㎡, building height 19 meters.
Roof style: Single-eaved four-sided pyramidal roof, covered with standard yellow imperial glazed tiles, topped with a huge gilded bronze finial. The square hall body plus round roof spire embodies the ancient Chinese philosophy: heaven is round, earth is square.
Facade layout: Open doors on four sides; exquisite golden dragon painted decorations on beams and brackets, golden dragon patterns carved on the ceiling. Bluestone golden bricks are paved on the indoor ground.
Interior layout: A carved dragon imperial throne is placed in the center. Two mythical beasts named Luduan stand beside the throne. Legend says Luduan masters multiple languages and predicts fortune, symbolizing the emperor’s wisdom and insight. Two imperial sedan chairs used for traveling inside the palace are also displayed here. A horizontal plaque inscribed Uphold Impartiality was written by Emperor Qianlong.
3. Core Functions in Ming & Qing Dynasties
Unlike Taihedian for grand public ceremonies, Zhonghedian served as the emperor’s exclusive preparation lounge:
Rest & ritual preparation before grand ceremonies
Before the emperor attended grand celebrations (New Year’s Day, Winter Solstice, emperor’s birthday) in the Hall of Supreme Harmony, he would rest, adjust ritual costumes and accept salutes from ritual officials and bodyguards here first故宫博物院.
Review sacrificial documents and ritual supplies
One day before worshiping the Temple of Heaven, Temple of Earth, Ancestral Temple and Altar of Land and Grain, the emperor came here to check sacrificial texts. Before the farming ritual at the Temple of Agriculture, he inspected grain seeds and farm tools to be used in the ceremony.
Formal review of royal genealogy
The imperial family tree (Royal Jade Genealogy) was revised every ten years in the Qing Dynasty. The finished genealogy would be presented to the emperor for approval inside this hall with formal rituals.
Temporary reception of nobles and ministers
Occasionally the emperor met Mongolian nobles and senior officials to discuss trivial state affairs in this hall.
4. Cultural & Architectural Value
As the transitional building of the three grand halls, Zhonghedian balances the solemn momentum of Taihedian and the practical function of Baohedian in spatial layout. Its neat square structure and exquisite wood carving art perfectly reflect the strict feudal ritual hierarchy and ancient Chinese architectural aesthetics. Nowadays, it is an important protected relic of the Palace Museum, showing the ritual order of ancient Chinese imperial power to visitors worldwide.
Short Version (for oral speech / homework presentation)
The Hall of Central Harmony is the middle and smallest building of the Outer Court’s Three Grand Halls in the Forbidden City. Constructed in the early Ming Dynasty and renamed in the Qing Dynasty, it adopts a special square pavilion-style roof. It mainly worked as the emperor’s preparation room before large-scale ceremonies in Taihedian, where emperors rested, checked sacrificial scripts and accepted officials’ greetings. The unique shape and interior cultural relics fully interpret traditional Chinese Confucian thoughts and superb ancient architectural craftsmanship.
