Thesis
After describing tea’s benefits, Chapter One suddenly says “tea can be a burden”. This is not a rejection of tea. It is a warning that careless picking, adulteration or excess can turn a good thing into a bad one.
The ginseng analogy makes the same point: a tonic can harm through wrong provenance, preparation or dose. The word 累 carries the sense of entanglement and burden. It keeps the Classic of Tea from becoming a advertisement; Lu Yu retains a wariness toward the thing he loves.
Contemporary tea culture needs the warning more than ever. Famous mountains, vintages, packaging and price can all become burdens; performance, comparison and over-drinking can turn tea from daily pleasure into pressure. Lu Yu plants the warning in Chapter One, which is why the chapter is not naive.
