@Iluviaporos - I remember reading a book which covered some of the wars China had gone through in the past. One of the characters was philosophical about encroaching armies and said that whether they took the country or not, they too would be considered Chinese by the time another generation had passed.
I'm not sure which dynasty that timeline followed, but they were all torn by war, as far as I can see.
It's a wonder they managed to make so many beautiful works of art and invent so many engineering marvels when they were always at war with someone.
If you look up the artifacts of the second Jin Dynasty (sometimes called Jinn to differentiate it from the first) you will see some beautiful statues and jade work that's been found in temples and grave sites all over China.
