This decorative painting is handcrafted using the enamel painting technique, which is known as the queen of colored porcelain. It undergoes twelve intangible cultural heritage processes, including making the base, filigree, blue dot, blue firing, polishing and gilding. It is wear-resistant, sun-resistant and remains fresh over time. The filigree lines in the details of the picture are delicate and smooth, either outlining the contours of mountains and waters or embellishing flowers, birds and branches. Each stroke embodies the artisan's years of skill accumulation, making each painting a unique piece of art.
