The first episode in the series focuses on Chang-an, which in modern-day China is called Xi-an. It was formerly the capital of China and the source of the Silk Road which ran from there to Rome. In ancient times it was the largest city in the world.
Tomorrow I start posting the 12-part Silk Road series. I found this series about 2 years ago, and have watched it all the way through three times by now, and individual episodes at other times.
Here is an animated video in the sumi-e style of painting. The film is inspired by Toaist thought and includes drawing of the Yin and Yang symbols as well as the I-ching.
