Strange Things in the Mountains of Daxinganling

I am the last forest guard in Daxinganling. Never open the door when the mountains are closed by heavy snow. The fire turns green, don't talk. The cry in the woods, don't look back. There are too many secrets hidden in this old forest that cannot be told. Every story happens late at night when you can't even see your fingers. A short unit drama, one chapter is a ghost story, not for the faint of heart!
