The reasons why the Forbidden City, Dongling and Beiling are included in the world cultural heritage.

1987, the Forbidden City in Beijing was listed as a world cultural heritage. The World Heritage Organization's evaluation of the Forbidden City is: "The Forbidden City is the highest power center in China for more than five centuries. It has become a valuable historical witness of China's civilization in the Ming and Qing Dynasties with its garden landscape and a huge complex of 9,000 rooms containing furniture and handicrafts.

Dongling: In the site selection and planning and design of the mausoleum, China's traditional geomantic theory was fully used, which reflected the world outlook of "harmony between man and nature", and fused the human spirit with nature, resulting in a lofty, great and immortal image. On the scale and quality of the building, we strive to be magnificent, spectacular and exquisite, so as to embody the idea of the supremacy of imperial power and show off the royal style and majesty, thus becoming a symbol of the materialization of imperial power. As one of the royal cemeteries in the Qing Dynasty, the Qing Dongling is the immortal carrier of this traditional culture.

The management of the Dongling Mausoleum in the Qing Dynasty spanned two and a half centuries, which was almost the same as that of the Qing Dynasty. There are many outstanding figures who have an important influence on the history of the Qing Dynasty, which contain rich historical information. It is not only a precious material for studying the laws and regulations, funeral system, sacrificial ceremonies, architectural techniques and crafts in the Qing Dynasty, but also a typical example for studying politics, economy, military affairs, culture, science and art in the Qing Dynasty. The Mausoleum of the Eastern Qing Dynasty is of great historical, artistic and scientific value, and it is the cultural heritage of the Chinese nation and all mankind.
