Thesis
Read through modern tea science, “晋时吴兴太守陆纳谢安来访纳所设惟茶果而已” is not a lab result but a set of variables: cultivar, soil, light and plucking standard.
Text
“In the Jin, Lu Na, governor of Wuxing, when Xie An came to call, set out only tea and fruit.”
Context
吴兴：今浙江湖州。陆纳：东晋名臣。谢安：东晋名相。茶果：茶与果品。
Evidence
- Collation: 各本一致。此典为"以茶待客、清廉简朴"的著名范例。
- Existing readings: 吴觉农评此典：陆纳以茶果待谢安，不以酒肉铺张，是"俭德"的具体实践——后世"茶礼"之重俭，源头正在于此。
Analysis
Modern tea science would split “晋时吴兴太守陆纳谢安来访纳所设惟茶果而已” into cultivar, soil, light and plucking variables. 吴觉农评此典：陆纳以茶果待谢安，不以酒肉铺张，是"俭德"的具体实践——后世"茶礼"之重俭，源头正在于此。 They remain testable, but only with their conditions attached.
Conclusion
The section does not give a universal rule. It demonstrates a method: read the text, the annotation and the Tang context together before making a modern claim.
