1. Imperial China
There have been mentions that the Doctor has been to China, but never a full on episode. It should be done and for many of the same reasons that the African episode should be done. There is too much bias in where Doctor Who is placed. Ancient China is really underestimated in its importance to world heritage. They were master mathematicians and astronomers. They invented tea (sorry Britain), fireworks, and many other things that today's society takes for granted. Aesthetically, this could be a beautiful episode and the storyline could potentially be amazing, too. There are so many historical characters to meet besides even the Khan family. Also, the Terracota Soldiers could be used in a storyline and used really well - making them alive has been done to the ground, too, but the creation of them might actually make a really good plot.
