I guess it was not just a coincidence that those amazing rock arts by unknown artists are located by Issyk Kul. In 1985, group of archeologists were able to find a whole civilization under Issyk Kul lake and it was the remains of an ancient city Chigu Chen, the capital of Usuns.
They found enough amount of proofs to the chinese ancient scripts. Only in those books were written all detailed information about this strong empire, even to the fact that how they called the first or second chinese wife of the Usun king. There were also the household items, such as dishes, arms, tools for farming and harvests, etc.
Those findings, put together with accurate history books can give the reader a great idea of lifestyle, culture and traditions of Usuns and all nations connected with them at the very beginning of our centuries.
