Alpha Centauri
The Chinese colonized Xin Shi in 2115. It is the closest planet to Alpha Centauri B, tide-locked with one side perpetually facing her sun. That side is far too hot for us to live normally, and even Africans prefer to avoid it. The far (dark) side of the planet is too cold for anyone but a Tibetan. Most people live within one hundred kilometers of the edge of the world, the ring where sunlight and starlight meet. They call it the Great Wall of Xin Shi.
