Sugar painting is ususally made with melted brown or white sugar. Craftsman often paint animals and flowers on a stone board with the syrup. When the sugar cools down, a piece of sugar art is finished.

"The most important thing is brewing sugar. If the temperature is too high, the sugar color will darken and won't be that transparent and beautiful," Li said.

Li said he loved painting when he was young, and he found it easy to learn the artistry of sugar painting.
