I love china, it is so exotic, I wonder when it was founded .
it's beautiful!  I know in the 3rd Centrue, BCE the Qin unified core China and established the first  dynasty
Oh, how long did the first Dynasty of China lasted ?
I'm not sure but the Han dysnasty was from 206BCE-220CE led by Liu Bang, which was the 2nd Imperial Dynasy
How the Han dynasty was formed ?
it was founded by the peasant rebel leader Liu Bang, known after his death as Emperor Gaozu
That is an interesting fact, and how the Han dynasty ended ?
the third and final capiral of the dynasty was Xuchnag that was mvoed 196CE, and there was a period of political turmoil and civil war that ended. 
OK, its there any monument (castle, temple) still standing from the Han dynasty ?
I am not sure but ther written records of the history of china date from as early as 1500 BC, from the Shang dynasty (c1600-1046 BC)!
