With nothing to break them down, the dead mosses pile up, preventing oxygen from entering the bog.

没有什么可以分解它们，死去的苔藓堆积起来，阻止氧气进入沼泽。

Fresh mosses piling up indigo, White clouds like jade afloat, And luminous sheens of mist and smoke; Emerald moss piled up in heaps of blue, White clouds like drifting jade, While the light flickered among wisps of coloured mist.

虚窗静室，滑凳板生花。
