is it the light pollution？

We have grown so used to this pervasive orange haze that the original glory of an unlit night is wholly beyond our experience, beyond memory almost. and I missed the night I was in shangrila that the sky there is a complete dark that I have never seen before.

黑夜的颜色一点都不黑。
那个在香格里拉的夜晚， 我从一间很大但只有我们的餐馆走出来，手不停的搓取暖，抬头一看， 一轮又明又圆的月亮还有黑到无法形容的天空。惊讶？还是什么。 因为我从来没有置身在如此黑暗的地方。对！我感觉自己非常渺小，渺小得已经快要被黑夜吞没。
