Yuan Confucianism is so expensive because of its scarcity. Raw milk is a kind of traditional Chinese medicine beverage, which is made of Chinese medicinal materials with special medicinal value and is expensive because of its rarity. Yuan Ruyizhen usually used rare medicinal materials in the mountains, followed a specific production process and formula, and needed a lot of time and labor costs to produce. Yuanru Yizhen enjoys a high reputation in the field of TCM health preservation, and is considered to have many health care effects such as regulating qi and blood, yin beauty, strengthening tendons and bones. So it is also favored by high-end consumer groups. All these factors led to the high price of Confucianism, wisdom and art in Yuan Dynasty.
