I just added two pin zi ni Yixing teapots to my seemingly never-ending teaware sale; an old 1980's ying huaand a newer xi shi (both sold), for anyone who's interested. Every addition reminds me just how many pots have passed through my possession, but I suppose it's better to help them find an owner who'll use them more instead of letting them languish in my tea cabinet, and past sale customers seem pretty satisfied providing loving homes.
For Westerners without the means to travel to Asia, our knowledge and experience of tea comes second-hand, with a healthy dose of mystery. Therefore, it's tough to really know anything for sure, let alone make claims about being any sort of expert. Instead, we can only enjoy and learn from small tastes of something ... smuggled in ... hopefully building a reliable knowledge base and maybe even scratching the surface of truly great tea.
