What is the painting method of treading water in Jingdezhen?

The painting method of Jingdezhen treading water gradually falling into the water. At the end of the Ming Dynasty, the Zhu Ming regime was in turmoil. With the transformation of traditional society in China, the cessation of imperial kiln factory and the stimulation of overseas markets, the porcelain production in Jingdezhen presents an unprecedented new atmosphere. As far as blue and white porcelain is concerned, there are many new expressions. The gradual collapse painting is one of the new paintings that appeared at that time. This method of porcelain painting can't be found in the literature, but it is circulated among the people in Jingdezhen. An earlier example we see now is the blue and white scenery painted on tanks, which were salvaged from the sunken ship Hatcher in the southern waters of Singapore in the late Ming Dynasty.
