Painting is made by hand-depicting the process of paint, the process paint of the painting is diluted according to a certain proportion by the use of thinner, and then by the manual according to the designed pattern, painted with a special hand-painted pen, and then placed to wait for the process paint to dry, the painting process is completed.
