The passage
“The fu cauldron is made of raw iron. Its inner mold is clay, so the inside is smooth and easy to scour; its outer mold is sand, so the outside is rough and endures the flame.”
Practice today
Bring “The fu cauldron is made of raw iron. Its inner…” to a modern table through one concrete session: choose water, heat it, warm the vessel, measure leaf, pour, and notice.
You do not need Tang-style pressed tea or expensive utensils. Start with clean water, a sensible temperature, and a clean finish.
The point of reading is not nostalgia. It is a better question at the tea table.
Reading note
Read the passage once for the image, once for the judgment, and once for the practice it implies.
Practice
- Name one thing the passage asks you to notice.
- Compare it with a tea you know.
- Keep the question open.
