Middle Kingdom was used to refer to civilizations around the Yellow River Valley before the empires leading to modern-day China began to form. The court cards use exquisitely detailed line art of Chinese deities and people, while the card back is a great freehand drawing with interpretations of Chinese lattice borders and of course, a dragon. China's vast history provides a rich palette of subjects for court cards. King of Hearts: Pangu, the first living being and creator of the Earth from chaos. King of Diamonds: Caishen, the main Chinese deity of prosperity. King of Clubs: Huangdi, the Yellow Emperor, creator of the centralized state. King of Spades: Tai Di, the "Primordial Divinity" or "Utmost God". Queen of Hearts: He Xiangu, an immortal renowned for her selfless caring for others. Queen of Diamonds: Lan Caihe, an immortal portrayed sometimes as a man dressed as a woman and other times as a woman, Lan Caihe was said to have ridden to heaven on the back of a magical swan while in a drunken stupor. Queen of Clubs: Xi Wangmu, Queen Mother of the West. She held court and allowed deities to meet in her perfect palace. Queen of Spades: Nuwa, humanity's creator along with her twin brother, Fuxi.

Fantastic creatures play a large role in Chinese mythology, and they are honored representing the suits: Phoenix (Hearts) - Sun, warmth, and love. Kui (Clubs) - A one-legged ox that would warn of coming storms. The Yellow Emperor (the King of Spades) used Kui's skin for a drum that could be heard hundreds of miles away. Pixiu (Diamonds) - Brings in good luck and wealth and drives away evil. Dragon (Spades) - The most powerful creature. The card back combines a dragon with another famous Chinese element, the Yin-Yang symbol. This symbol represents positive and negative, order and chaos, male and female. Combining elements of Chinese architecture, latticework, and dragon art, the tuck box is the perfect complement to the cards.
