Puer Tea Glossary - Zhi Zheng Tea Shop

„chui niu; 吹牛. 吹 - chui, to blow. 牛 - niu, cow, but in this case can be read as 公牛 or bull. An almost default aspect of tea drinking - 'shooting the bull'. The talk that often accompanies tea drinking and can be peppered with much knowledge, a little exaggeration and some humour. Also 吹牛皮. 皮 - skin or hide. 'Blowing the bulls hide.'“

„The fermented dark tea, Hei Cha (黑茶), is one of the six classes of tea in China, and pu-erh is classified as a dark tea (defined as fermented), something which is resented by some who argue for a separate category for pu-erh tea.“
