从某个角度上说,人类的历史,也是人类对树叶的认识和利用史。从遮羞到贝叶经,其次到叶脉画,再到纸张,再到微量黄金,人类对树叶的认识和利用史,也是一部从初级到高级的进化史。那一片遮羞的树叶颇具象征意义,我们可以把它看成是人类最早最初级的文明标志,也是人类对树叶有意识的最早的利用。 From a certain angle, the history of mankind is also the history of man’s knowledge and utilization of the leaves. From the shame to the Bayeux, followed by vein painting, and then to the paper, and then a trace of gold, human understanding of the leaves and the history of use, but also from the beginning to the advanced evolutionary history. The leaf of a hideous leaf is quite symbolic, and we can regard it as the earliest and most primitive symbol of civilization of mankind and the earliest utilization of human consciousness of the leaves.
