The name 蝙蝠汉瓦 literally reads “Bat — Han (dynasty) Tile.” This exact label is not a widely established traditional teapot type in reference works, so the following is a cautious, general description based on the components of the name and common Chinese ceramic practice.

Brief history/context: Bat imagery (蝙蝠, bianfu) is a long‑standing auspicious motif in Chinese decorative arts because the word for bat (fu) is a homophone of “good fortune” (福). Bats appear on porcelains, bronzes and teapots from the Ming and Qing periods onward. The element 瓦 (tile) and the reference to “Han” likely allude to Han‑dynasty roof‑tile shapes and瓦当 (tile‑end) ornamentation, which have inspired later ceramic forms and relief decoration. Chinese teapot makers—especially within the Yixing zisha tradition and studio pottery circles—routinely adapt architectural motifs (tiles, bricks, rafters) into imaginative teapot silhouettes.

Shape note: A “蝙蝠汉瓦” teapot would typically pair a compact, low body evocative of a tile or roof segment (flat or gently ridged) with bat decoration in low relief, incised carving, or an applied knop. Expect a stout, short spout and a practical loop or integrated handle; finishes may be unglazed clay to emphasize texture and color. If you provide a photo, I can give a more precise identification and tailored description.
