To mark the status and signify the power of a palace (or its owner), the number of decorative mythical creatures on the ridges of the roof was carefully designated. The more important the palace, the greater the number of these figures.

 

Ordinary palaces typically had three to five such statues, while the Hall of Supreme Harmony (Taihe Dian) is the only structure in the Forbidden City that features ten mythical creatures on its roof.

 

 The ten creatures are arranged in a specific order, each carrying symbolic meaning:

1. Dragon (Lóng, 龙): A symbol of the emperor, representing good fortune and supreme authority.
2. Phoenix (Fèng Huáng, 凤凰): In Chinese mythology, the phoenix is the king of all birds. Its presence symbolizes peace and prosperity, bringing blessings to the people. Like the dragon, it is also considered a noble and mystical creature and represents the empress.
3. Lion (Shīzi, 狮子): A symbol of courage and majesty, ensuring the safety of the palace, bringing good fortune, and warding off evil spirits.
4. Heavenly Horse (Tiān Mǎ, 天马): Represents auspicious omens and good luck.
5. Sea Horse (Hǎi Mǎ, 海马): Has the ability to turn misfortune into blessings. This mythical creature is also considered a guardian of royal dignity.
6. Suān Ní (狻猊): A lion-like mythical beast known for its ferocity. It is believed to suppress natural disasters and reduce evil influences.
7. Yá Yú (睚眦): A creature that combines fish and beast characteristics, often regarded as the leader of all fish. It is associated with the "Rain Dragon" (Shuǐ Lóng, 水龙) and is believed to summon rain, extinguish fires, and prevent calamities.
8. Xiè Zhì (獬豸): A unicorn-like creature that symbolizes justice and righteousness. In ancient Chinese culture, the Xiè Zhì was believed to distinguish between good and evil and was a representation of fairness and law.
9. Dòu Niú (斗牛): A mythical ox or water buffalo that brings good omens, protects homes, and wards off disasters and evil spirits.
10. Xingshi (行什): A small, unique beast believed to protect against lightning and dispel misfortune.
     

These mythical figures not only reflect the hierarchical structure of Chinese imperial architecture but also embody deep cultural and spiritual significance.
