The rings on the stump record decades of shifting climate.
Tips
memory
A year-wheel: 年 plus 轮. One ring is laid down per growing season, wide in a good year and narrow in a dry one, so counting outward from the centre gives the tree's age.
culture
Chinese writing reaches for it figuratively as well, for the marks time leaves on a person or a place: 岁月的年轮, the rings the years leave behind. English has no comparable ready-made image, so translations usually unpack it.
