From all my observations, currently the Lost Civilization has it's presence in the desert, the desert ruins, and the Arctic regions. The arctic ones being converted to Outlanders cities and monuments.  
  
However I'd like to see buildings and some materials in the Eastern side. This could enrich the buildings and the other areas of gameplay. While we do have some slight resemblance to it, via the bamboos and the lost world underground, just like by the book of Jules Verne, it hopefully isn't the exact final result of it.

I've compiled some images for references, for instance the roofs should have the characteristics of the architecture, that is the corners of the roof rising upwards slightly. \[See Image 1\]

The brazier could be a dragon base holding on top the actual flame. \[See Image 2\]

As for the statues, there can also be two of them.\[see Image 3 and 4\]

As for the pillars and similar, they can be made using wood, Red wood or red oak. Which then can be expanded for pillars or similar\[See Image 5\]

As for the enemies/Neutrals within\[See Image 6\] the reference similar to the image. OR for more inspiration see Jackie Chan movie "The Myth" 2005

 Does this have to be part of Lost Civilization? No, not necessarily. Rome and China knew of each other, they lived around same time. Therefore it's possible even in Hytale to have Cousin Civilizations who have fallen. 

This could also be a great excuse to have Katana or as known in China The *wodao*  'Japanese sword'

As for the actual structure in game, I am thinking either an intact Forbidden City, or it's unfortunate ruins.

If anyone is interested to make a mod for this, I'd be happy to help out. I have some acquaintances from China who can give some ideas/explanations. 

BONUS: We could have Daji in game :3 

[Update/Mod Request] Eastern presence. A branch/cousin of the ancient Empire.
