Xing

Xing is a nation ruled by an Emperor on the eastern far side of "The Great Desert." Not much is known about it, because it's so far from Amestris.

Location
Xing is to the east of Amestris, separated from it by a great desert. There is also a water route to Xing from Amestris, but it is considered to be "the long, but easy way around". Xing's overall size is also much bigger than Amestris.

Culture
Xing is ruled by emperors who take a wife from every clan of Xing, giving every clan a chance to get to power. However, most clans are very small and it is not uncommon that rival clans make assassination attempts against rival princes or princesses. Two known clans are the Yao-clan, from which Ling Yao, Lan Fan and Fu come from and Mei Chans clan. The clans seem to be rivals, as Mei Chan and Lan Fan fight in Dr. Knox's apartment.

Technology
The people of Xing have developed hand grenade-like weapons that come in many variations, ranging from flashbangs to explosives. Xing don't seem to use firearms, as Fu was clearly shocked to see how powerful cannons can be.

Alchemy
The Xingese do not use Alchemy like the Amestrisians. Instead they use another form of such being used to form medical purposes. They haven't discovered a way to use their version of Alchemy in war yet. Also, unlike Amestrisians, they believe their Alchemical powers come from Earth's veins, called "The Vein's of Dragon".

Trivia

 * Xing can be considered the equivalent of China in the world of Full Metal Alchemist, as people are very skilled in martial arts and have invented portable explosives.
 * The Xingese were taught alchemy by the wise man from the west.
