I want to know the answer to the following question:
When did the Chinese use diurnal rhythms to remember Acu-points?
All the background I'm provided with is that "The earliest recorded account of a circadian process dates from the 4th century B.C.E., when Androsthenes, a ship captain serving under Alexander the Great, described diurnal leaf movements of the tamarind tree.". Is that enough to answer the question?
Answer: no
