Yumenguan , Dunhuang (Jade Gate).

Uncultured winds move over mountains, through trees, across stones howling cold against a wall and a gate.

Jade the familiar;

...now the colour of the unknown, of barbarian deserts and the limits of a middle civilization.

...now the colour of adventure, of escape, and of a new life waiting ...and just as easily the end of this one.

Uncultured winds and a hard unassured path, trodden with intrepidation.
