Walk into Huqingyutang — founded by a Qing-dynasty merchant, still "Jiangnan's Medicine King" after 140 years. The front shop still dispenses; the back workshop still grinds. Watch a pharmacist weigh herbs by hand, then browse a thousand specimens in the museum. Next, stand before an AI that reads your tongue and face, generating a body-constitution report in three minutes. Then roll your own moxa stick from raw leaves. Finally, a robot's infrared arm finds your acupoints — heat-sensitive moxibustion, delivered with mechanical precision.
