Where is a Chinese medicine shop in Xuzhou? Without a prescription, just buy some medicine such as boat-fruited Sterculia! It's not big!
Things like boat-fruited Sterculia are sold in any drugstore. At present, most pharmacies in Xuzhou have Chinese medicine counters, which can be bought by pharmacies in general communities. I have several medium-sized pharmacies in the lakeside community. Besides boat-fruited Sterculia, I suggest buying some cassia seeds to make tea, which can lower blood pressure and improve eyesight.
