Wu Cheng'en said this quote
“ The earth is black in front of the cliff, and no orchids grow.Creepers crawl in the brown mud by the path.Where did the birds of yesterday fly?To what other mountain did the animals go?Leopards and pythons dislike this ruined spot;Cranes and snakes avoid the desolation.My criminal thoughts of those days pastBrought on the disaster of today. ”
