Dividend original: 實 (shí); the number being operated upon.
Tail (Nine) Start the chant: Five times nine is forty-five; change the nine to a five, and add five to the position below.

Positioning
This is the dou A "peck," 1/10th of a shi. unit; the circle moves backwards to determine the place. Harmonize and obtain the result.

(Six) original: 吝 (lìn); here used as a mnemonic marker for the digit six. Chant: Five times six gives thirty; change the six to a three.
(Stone) original: 石 (shí); a unit of weight/volume. In this method, there are five dou of cinnabar for every shi. Stop at the shi position; the next position down is the dou.
(Four) original: 早 (zǎo); here used as a mnemonic marker for the digit four. Chant: Five times four gives twenty; change the four to a two.
(Tens)
Head of the Dividend (Two) original: 靑 (qīng); here used as a mnemonic marker for the digit two. Chant: Five times two gives ten; change the two to a one.
Original (Hundreds): Start the chant from the hundreds and move backward. Count in order until the shi is reached to match the (Hundreds).
(Unit) (Ten) (Stone) (Tens) (Hundreds)

Table of Doubling Rules

These rules are used for division by 5; since dividing by 5 is the same as multiplying by 2 and shifting the decimal.

For five-one, double it to make two. 1 ÷ 5 = 0.2
For five-two, double it to make four. 2 ÷ 5 = 0.4
For five-three, double it to make six. 3 ÷ 5 = 0.6
For five-four, double it to make eight. 4 ÷ 5 = 0.8
When meeting five, advance ten. 5 ÷ 5 = 1.0; move to the next rod on the abacus.

Suppose there are currently 33,569 logs of cedar wood original: 杉木 (shānmù); specifically the Cunninghamia lanceolata, widely used in Chinese construction.. Each log is priced at 6 fen A unit of silver currency, often called a "candareen" in Western historical contexts; 100 fen equal 1 tael (liang). of silver.
Question: What is the total amount of silver required?
