Blue and white double-circle six-character double-line books are placed at the bottom of bottles, cans, bowls, washing, pots, plates and other utensils. Cans, pots, bird food cans, cross-grain stoves, pie plates, Gao Zuwan and other utensils are all written with six-character banners. The six-character vertical body is generally written on the incense burner, the middle of the bowl and the handle of the pot. Four characters are generally written on the shoulders of bowls, Gao Zubei bottoms and plum bottles. Gao Zuwan's style is generally in the heart of the bowl, mostly double-circle six-character. The plates are glazed books and sand books, engraved on the shoulders, sides or under the hem.
The structure and layout of Xuande's blue-and-white brush strokes are very regular, the distance between words and the thickness of brush strokes are moderate, imitating the brush strokes of Jin and Tang Dynasties and having the charm of Yan calligraphy. Strong brushwork, neat handwriting, dignified structure, clear font, rich and concise. Mr. Sun Yingzhou, an expert in ancient ceramics, summed up his understanding of Xuande's style and wrote a song saying: "Xuande's style is perfect, the seal cutting is dark and yin and yang, and the flowers are four pairs of single gardens, with the Jin and Tang Dynasties being the most prominent." The word "big" in regular script is short and long. There is no horizontal word "virtue" and "heart", which is an ancient style writing method in Han tablet. The left and right parts of "virtue" are closely related and seem to be out of harmony. The horizontal edge of the word "Yi" in the word "Zhi" does not exceed the word "Dao", and the tick of the fourth stroke of the word "Yi" is not connected with the left of the fifth stroke. There are few seal scripts written, and the double circles often have shades. The six-character part has different sizes, the font is clear and round, and the pen head and tail are pointed. There is a horizontal line on the heart of the word "De". The left side of the word "Xuan" is a little more than the horizontal line, and the right side hangs down. The horizontal line of the word "one" below the word "zhi" is shorter.
