封
ふう
- head-high (atamadaka): falls after mora 1
How to read it: a line over a kana means the voice is high there, and ↓ marks where it drops. A kana with no line is low. With no ↓ the pitch stays high to the end and does not drop even on a following particle (が, は).
seal
Fū, “seal”, is derived from Middle Chinese 封 (MC pjowng|pjowngH).
