Sui Dynasty from 581-618, a short but an important dynasty. He brought an end to troubled times over the past 300 years. He ccreatively built new government system and examination system which were used all the time after that.

In fact , Tang dynasty is affected by these systems - the three systems and six departments , inviting the public exam for every government officers and end the south and north dynasties with about 400 years.

Yueng kin is a more vital emperor than Mr's Lee Sing man who is second emperor of tang dynasty.

Do you think how tang dynasty became rarely stronger in 2000 chinese history sometimes ? Why the women in Tang dynasty can be open and respected ? I think it should be found in sui dynasty even though it is very very short , which only have 37 years period and that can be diseasblished by the tang dynasty.
