What is a traditional battle?

The technique of "one hemp and five ashes" in the battle of ancient architecture painting is just a layer of hemp and five ashes contained in the battle. Gu Lou's paintings have not only one hemp and five ashes, but also one hemp and four ashes, two hemp and six ashes, four ashes, three ashes and two ashes without hemp. No matter how to increase or decrease the construction procedures, the process principle is the same as "one hemp and five ashes", so we all take "one hemp and five ashes" as the representative of the traditional painting practice of ancient buildings. One hemp and five ashes include catching seam ash, sweeping ash (also called cleaning ash), pressing hemp ash, medium ash, fine ash and hemp making.
