"I had wanted to do the solar terms series for a long time, because the related rituals have preserved the romance that belongs to Chinese people," the sand painting artist says, adding that those terms are ancient wisdom that has been obtained through constant exploration over the long course of history.
"I want to use sand painting to show the passage of time and our farming civilization," He says.
