There is an ice wall under Kunlun Mountain, and there is a door behind the ice wall.
The door is ajar and has been ajar for six thousand years, waiting for someone to push it open.
Chen Mo didn't know this at all. He collects scraps in the south of the city, lives in a tin shed, and rides a broken tricycle through the streets every day. He only has one book, left to him by his grandfather, with a blue cloth cover and "Commentaries on the Classic of Mountains and Seas" written on it. He turned it over many times and recognized every page. It was just as much a part of his life as the waste paper box.
Until one day, the sky cracked. Blue-grey light leaked from behind the clouds, and several winged things fell out of the cracks. He opened the book. It was getting hot, and there was an extra line on the title page: Guixu has been opened. The pillar of heaven is broken. The beasts travel south.
He did as the book said and used a handful of cinnabar powder to scare away the strange bird with a human face. Later he went to Kunlun. The door behind the ice wall was engraved with his father's name - Chen Jianguo. He entered this door in 1998 and never returned.
Three generations, sixty-two years. A book that writes by itself, a door that never closes.
"Doors are not meant to be closed." The book reads.
Chen Mo stood in front of the door for a long time. The wind blew over, carrying the smell of dry earth and old paper. He glanced down at the book. The blue cloth cover was warm in his palm, as if something had been awake between the pages, waiting for this day for a long time.
He took a step. The book, the door, and the wind accumulated over six thousand years are all behind him.
——The book should be warm when you turn the first page.
