白 木材，春木和秋木之间颜色差别非常小。

Wood moved slowly, but not equally, with its mixture of springwood and summerwood, straight and wavy grain, knots, rings and imperfections.

Wood moved slowly, but not equally, with its mixture of springwood and summerwood, straight and wavy grain, knots, rings and imperfections. And it would always go the way it was naturally inclined.
