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.'“

„Nèi fēi (内飞 or 內飛): A small ticket originally stuck on the tea cake but now usually embedded into the cake during pressing. It is usually used as proof, or a possible sign, to the authenticity of the tea. Some higher end pu'er cakes have more than one nèi fēi embedded in the cake. The ticket usually indicates the tea factory and brand.“
