Tolerance.
The way of tribute tea in the court pays attention to exquisite tea, exquisite tea art, complicated etiquette and distinct grades. Song Huizong and Evonne said in "Daguan Tea Theory" that tea is "clear and harmonious", "light and concise, high and quiet", which shows that the court tea ceremony also has the characteristics of educating the people. In the Song Dynasty, "Doucha", characterized by fighting for fragrance and taste, was still popular among the people.
In the Ming Dynasty, Zhu Quan reformed the tea ceremony, integrating Taoist thought with tea ceremony, and pursuing the realm of following nature and returning to nature. At the end of Ming Dynasty, Feng Kebin described some taboos of drinking tea and advocated "harmony between man and nature", which was a step further than the tea ceremony in Evonne. Zhu Yuanzhang, the Ming emperor, changed brick-cake tea into loose tea, and tea developed from cooking to brewing. The procedure is from complicated to simple, paying more attention to the quality of tea itself and the atmosphere and environment of drinking tea, and returning to the original.
