Tea Manual by Zhu Quan, aka Prince Ning, 17th son of Ming dynasty founder Emperor Hongwu in 1440, is a milestone work.
Following his father Emperor Hongwu's ban on manufacturing of tea cake, Prince Ning advocated a simpler way of steeping loose tea, a radical departure from the sophisticated tea cake ceremony of Tang and Song dynasty, thus pioneered a new era in Chinese Tea Culture.
Prince Ning also invented a tea stove called "Koojiejun".
