Application
The di mo is applied to the membrane hole (or Mo kong) of the dizi using a special, traditional glue called Ejiao. One of the advantages of ar jiao is that the glue is water-soluble, so that it can be wetted again to re-adjust the di mo.
After applying the glue around the mo kong, the di mo is applied, and then adjusted while the glue is still wet so that many creases form in a sequence along the length of the hole. Each crease should be parallel to the one before, crossing the hole horizontally, so that together they form a sort of pleat or corrugation.
If Ejiao is not available, a substitute can be improvised by simply crushing garlic into a fine, relatively dry paste, and applying as normal. It should be used quickly.
Although the purpose of applying di mo is simply to make the dizi operational, the application technique is considered to be an art in itself.

Famous quotes containing the word application:
“It would be disingenuous, however, not to point out that some things are considered as morally certain, that is, as having sufficient certainty for application to ordinary life, even though they may be uncertain in relation to the absolute power of God.”
—René Descartes (1596–1650)
“Great abilites are not requisite for an Historian; for in historical composition, all the greatest powers of the human mind are quiescent. He has facts ready to his hand; so there is no exercise of invention. Imagination is not required in any degree; only about as much as is used in the lowest kinds of poetry. Some penetration, accuracy, and colouring, will fit a man for the task, if he can give the application which is necessary.”
—Samuel Johnson (1709–1784)
“Courage is resistance to fear, mastery of fear—not absence of fear. Except a creature be part coward it is not a compliment to say it is brave; it is merely a loose application of the word. Consider the flea!—incomparably the bravest of all the creatures of God, if ignorance of fear were courage.”
—Mark Twain [Samuel Langhorne Clemens] (1835–1910)
