True redaction removes the text and images from the file — not a black box on top. Plus real in-place text editing, fill + sign, reorder pages, and OCR.

Drop two versions of a contract or drawing set. Moved notes read as moves, changed values light up digit by digit, and hidden text is named.
LaunchSide-by-side or overlay PDF diff driven by one engine that reads each file into a structured model — text, vector geometry, images, form fields, annotations — and compares the models. Moves show as moves, edits show only where they happened, and any PDF type works without picking a mode.

Alcoholic drinks from Northern China
A 6th-century recipe from the Qimin Yaoshu for wine made with divine qu (shenqu), a wheat qu. The qu cakes are sunned, cleaned and crushed, soaked until they bubble, and then fed cooked glutinous millet or proso millet in four stages over six nights. A glutinous-rice version of the same method is credited to the household of Vice-Director Yuan. Made in 5 steps over 12 days – 14 days. The longest step, add the grain in four stages (酘), takes 6 days (Jia Sixie). Moulds and yeasts of the divine qu, which make the soaking qu bubble does most of the fermenting.
| Main step | 6 daysReported[qmys-ws][qmys-siku] | Add the grain in four stages (酘) |

| 1 dou | Divine qu (神麴) · Whole qu cakes, cleaned, sunned and crushed[qmys-ws][qmys-siku] |
| 5 sheng | Water for soaking the qu · River water is best for washing and cooking[qmys-ws][qmys-siku] |
| 2 dan 1 dou in all | Glutinous millet or proso millet · Washed about 20 times and cooked soft[qmys-ws][qmys-siku] |
| Starter | koji/qu/mold-starter (divine qu, a wheat cake starter) |
Total time across the recorded steps: 12 days – 14 days
What changes: Whole qu cakes dry in the sun and are brushed clean three times a day
Output: clean, dry qu cakes.

Divine qu is far stronger than the coarse ben qu. One passage in the same chapter says one dou of divine qu can ferment three dan of grain, against six dou for one dou of ben qu. The grain goes in small batches, and each wait between additions is a night longer than the last.
The text says to clean the qu of earth, to wash the grain about 20 times, to use river water, and to keep people and dogs from eating the wine rice.

Qimin Yaoshu chapter 64, 造神麴餅酒 (making divine qu cakes and wine), compiled by Jia Sixie in the 6th century. The text marks the glutinous-rice method as that of the household of Vice-Director Yuan. Divine qu, as described in this book, shaped later medicated leavens.
