Tips
usage
Mostly seen as a one-character abbreviation for Hangzhou in compounds: 沪杭 (Shanghai-Hangzhou), 京杭大运河 (Beijing-Hangzhou Grand Canal), 杭甬 (Hangzhou-Ningbo). The original 'ferry boat' meaning survives only in classical texts.
memory
木 (wood) + 亢 (kàng, phonetic). The wood radical hints at the original 'wooden boat / ferry' meaning, before the character became fixed as the city name.
