第一次注意它们,是少年的时候一次随母亲在承德的避暑山庄。那是一年的盛夏,北京呆不住了,母亲的单位组织到这里来游玩。想当初是皇上才能住的地方,自然应该很凉爽吧?可是,那年实在是太热了,走在山里,稀疏的树林还是挡不住酷暑的淫威,我们的衣服都贴在了身上。当时我想,这里有什么好?难道皇帝们就是这样避暑的么?抑或古时候的太阳没有这么热?还是那时候的树林子密呢? The first time they pay attention to them, is a boyhood time with his mother in Chengde Mountain Resort. It was a year of summer, Beijing could not stay, the mother’s unit organized to play here. It would have been cool to imagine the place where the emperor was able to live. However, it was too hot that year. Walking in the mountains, the sparse woods could not stop the desperation of the heat, and our clothes were attached to the body. At that time I think, what is good here? Is the emperor is so summer it? Or ancient times the sun is not so hot? Or when the woods sub-dense it?
