"Height" is a feature of the sky. The architecture of the Temple of Heaven is a continuous and rising whole. Seen from the north-south central axis, the dome at the southern end is 5.18m high, the imperial vault is19.2m high, and the outer hall rises to 38m, making it the peak of the central axis. The Hall of Supreme Harmony in the Forbidden City was the tallest building in the city before Yongle, and it was the symbol of the emperor. Magnified Nian Dian is 3 meters higher than Taihe Dian, becoming a symbol of Heaven Emperor.
Around the main building of the Hall of Prayer for the New Year, the walls are low and the space is open. The overall outline of the Hall of Prayer for the New Year and the dome is directly connected with the sky. The altar seems to soar into the sky, and the people standing on it seem to ascend to heaven. The lofty feeling of the Temple of Heaven contains the idea of respecting heaven.
"Circle" refers not only to appearance, but also to a scientific realm. In China's ancient aesthetics, reading represents the light turn of life, including all things in the universe, and embodies a kind of peaceful and harmonious spirit of "healthy heaven".
A prominent feature of the Temple of Heaven complex is a large number of circles. The dome, the imperial vault and the Hall of Prayer for the New Year are all round, and each building forms many concentric circles, extending to become a harmonious whole with the dome-shaped sky.
"Qing" is a characteristic of heaven and an aesthetic category in ancient China, which embodies a kind of personality spirit or artistic realm, such as freshness, halal, lightness and exquisiteness. "Green" comes from "Qing", and we usually call the sky "blue sky", "blue sky" and "sky". The overall tone of the Temple of Heaven is cyan, and the sky and glazed tiles belong to cyan. "Green" is a symbol of peace and tranquility, and it also embodies an ethereal beauty.
In the architecture of the Temple of Heaven, blue glazed tiles are used for the Hall of Prayer and the Royal Dome. The dark blue glazed tiles and the light blue sky are in contrast in color, showing the clarity and clarity of the sky. On the other hand, the clarification and clarity of the sky is in harmony with the reality of the external outline of the Hall of Prayer for the New Year, which arouses the aesthetic imagination of the viewers.
