Frugal spending and a prosperous people was an ideal of governance in antiquity.
Tips
usage
Standalone 裕 is rarely used in modern speech — you'll meet it inside compounds: 富裕 (wealthy), 宽裕 (well-off, plenty of room), 充裕 (ample), 余裕 (leeway). Think of it as the "-affluence" suffix character.
memory
Radical 衤 (clothing) on the left + 谷 (valley) on the right: imagine clothes piled valley-deep — that's 裕, abundance.
