I have such a big fondness for silk shirts and dresses, and it never stops reminding me of how silk started to serve mankind from 5000 to 8000 years ago.
I also admire how our ancestors tried to describe silk. Pictographically, they draw two bounds of silks twisted and hanging together like pictured below for 丝-silk.
It was never an easy job in breeding silkworms and drawing silk from silkworm cocoons, especially in the barbaric era. On top of promoting beauty and comfy in human lives, this hard work also served and serves as the crystallization of human wisdom, the pursuit of the art of a better life, and the result of trustful cooperation over processes and among groups.
As an important sign, the history of human beings develops in the process of continuous migration, and consequently, frequent exchanges of skills, agricultural products, medicine, ideas, religion, and culture occurred. Natural sciences, art, literature, handicrafts, and technology started to be shared and disseminated.
Such communication and trade crisscross the Eurasian continent gradually formed through two major roads: the land and the sea. These two roads were never easy nor short. They were just like two twisted roads stretching into the distance, bound together by one sacred goal.
