A Planet that Does Not Rotate

Chapter Intro: A planet that does not rotate
There is a planet that does not rotate, thus creat a place where there are only three areas on it: Fire, Ice and the only lively Osis. Part full of fire, or more accurately the lava, is unbearably hot, any living creature near it only 2 miles will go vaporated, with constant sunlight everthing is just bright and hot and firery. Part full of Ice is a place without any single sunlight in, pitch dark, but as you inching away from the bright place, the ice on the ground will actually make you see the white, dark mass formed by some weird plants becoming visible to the eye, not many of them though, as you look farther, it's just this foggy white to the eyes. Also the penetrating coldness, 2 miles near it, without things to generate heat, you will be frozen on this ice land in less half a day. While the middle part is much more promising than the two opposite ends: it divided by light and darkness, people themselves migrant from light to the dark for sleep and rest, and back to light for work and living, making the day much more single monotonous and concerntrated, thus make the most ability of one when he or she is aweak, making the night much more pure and constant. The resident houses are cut in half by light and darkness: human has to bath. With bath there is the washed clothes and sheets.
