What dynasty is onion ginger salt tea?

According to reports, before the Tang Dynasty, people poured tea and water into a pot, added onions, ginger, dates, orange peel, dogwood, mint and other condiments to boil, and drank soup after the water was boiled, without foam, which damaged the fragrance of tea. In the Tang dynasty, the way of drinking tea began to change gradually, and people summed up a new method: first boil the water, or add a small amount of salt to the water. After the water boils, pour in the tea leaves, boil it, and then drink it with water. There is considerable stress on the utensils used for drinking tea. Lu Yu pointed out: porcelain is the best tea set, celadon is the best porcelain, and Yue porcelain produced in Zhejiang is the best; Mountain spring water is the best water for tea.
