former or literary name for Nann
邕 is a rare kanji used as a former or literary name for Nanning, a city in China. Its standalone meaning is unclear outside of that proper noun context.
The exact historical development of 邕 is uncertain. It appears to combine 巛 (river) and 邑 (city), possibly suggesting a city by a river, but this is speculative.
The top 巛 looks like flowing water, and the bottom 邑 suggests a settlement. Picture a city by a river, which fits the old name for Nanning.
For ヨウ, imagine a city by a river where people greet you with a cheerful 'Yo!' — Yo! -> ヨウ, and the city is 邕.
