According to the history book, medieval to early modern times (by holt) answer the following question:
1b) explain how did chinese culture change during the period of disunion?
answer using pages 166-169. if you want to be really , then if you could do problems 1-4, that would be really kind of you. ; -)

Once the nomadic travelers finally arrived in northern China, a few of the Chinese mixed in with the nomads' culture, while the invaders adopted some Chinese practices. Some of the nomadic leaders ordered their people to use Chinese names, use the Chinese language, and dress like the Chinese. Many northern Chinese were against this new system to live under the rule of the nomadic invaders, and fled to southern China. There, northern Chinese culture mixed with the southern therefore developing a change in their culture altogether during the Period of Disunion.

I hope this helped! :D
