呛人的

One never thinks of China, but it is there all the time on the tips of your fingers and it makes your nose itchy; and long afterwards, when you have forgotten almost what a firecracker smells like, you wake up one day with gold leaf choking you and the broken pieces of punk waft back their pungent odor and the bright red wrappers give you a nostalgia for a people and a soil you have never known, but which is in your blood, mysteriously there in your blood, like the sense of time or space, a fugitive, constant value to which you turn more and more as you get old, which you try to seize with your mind, but ineffectually, because in everything Chinese there is wisdom and mystery and you can never grasp it with two hands or with your mind but you must let it rub off, let it stick to your fingers, let it slowly infiltrate your veins.

一个人永远也不会想到中国，可它一直沾在你的指尖上，叫你的鼻子直发痒。很久以后，当你几乎全然忘记了爆竹的气味之后，某一天你会被金箔呛醒，破碎的引人棍又送来刺鼻的气味，艳红的包装纸使你对根本不了解的一个民族、一个国土产生了眷恋之情。尽管你并不了解它，它在你的血液中流动，神秘地流动。像时间或空间这类时隐时现却又永恒的概念，越年老你便越仰慕它，试图用脑子去理解它，可是却不成功，这是由于中国的每一件事物中都孕含智慧和神秘，你无法用双手抓住它，也无法理解它，只得由它去，由它沾在你手指上，由它渐渐渗进你的血管中。
