养 (yǎng): To raise, to nurture, to cultivate, to care for. This character is the same one used for raising children (养孩子, yǎng háizi) or keeping a pet (养宠物, yǎng chǒngwù). It implies a long-term commitment of care and nourishment.
壶 (hú): Pot, kettle, or most commonly, a teapot. It is a pictograph of a vessel with a lid and a handle.
When combined, 养壶 (yǎng hú) literally means “to raise a teapot.” This beautiful and direct combination perfectly captures the essence of the practice—it's not a quick chore, but a slow, loving process of cultivation.
