A, B, C, D, x9, D, B, B, D, x4, D, B, B, B, D

Solution: A, B, C, D*, 9 D, C, B, A.

Namely. A 1 B 0 C 8

D 9 analysis: a four-digit number multiplied by 9, or a four-digit number, then A must be 1, by the product of the single digit is 1, to get Ding is 9, because only 9 times 9 mantissa is 1, then, the product is the first 9, in addition, is multiplied by hundreds of digits for 0, because even if it is 2, the 1200 multiplied by 9 can not get four digits, so B is 0, as for C, it is very simple to try one by one. Try to get 8, C is 8.

That is, 1089*9=9801

From the meaning of the title, it can be obtained (1000a+100b+10c+d)*9=1000d+100c+10b+a

If a> or =2, then the number must become 5 digits, and because a cannot be 0, a=1, then d=9

Because DCBA is a multiple of 9, a=1, d=9, we get 9|(1+9+c+b) gives c+b=17 or c+b=8

and from (1000a+100b+10c+d)*9=1000d+100c+10b+a, 10c-890b=80 can be obtained

Substituting c+b=17 and c+b=8 respectively to obtain.

When c+b=17, the solution b= does not conform to the problem, so it is not true, then a 2-element one-time equation can be obtained:

10c-890b=80

c+b=8 gives b=0, and substituting b=0 gives c=8

So a=1, b=0, c=8, d=9

Four-digit number * 4 = four-digit number, no carrying.

Then A is 1 or 2, because 4 * D must be even, so A must be 2, so Ding must be 8, A is 2, D is 8, so B * 4 has no segment cavity carry, so B is 1 or 2, because 4 * C + 3 = B, so B is singular, so B is 1, and then 4 * C grips the sedan shirt + 3 = B = 1 Push C is 2 or 7, and 2 is substituted into the sail pin to be 7

That is: 2178*4=8712

It is followed by: 戊 (wù), 己 (jǐ), 庚 (gēng), 辛 (xīn), 壬 (rén), 癸 (guǐ).

A, B, C, and D are the heavenly stems, which are used to arrange the years and dates, and the date of creation is 2,697 (2697) B.C.

Ten days of dry: 甲 (jiǎ), B (yǐ), C (bǐng), 丁 (dīng), 戊 (wù), 己 (jǐ), 庚 (gēng), 辛 (xīn), 壬 (rén), 癸 (guǐ).

Twelve earthly branches: 子 (zǐ), ugly (chǒu), 寅 (yín), 卯 (mǎo), 辰 (chén), 巳 (sì), 午 (wǔ), 未 (wèi), 申 (shēn), 酉 (yǒu), 戌 (xū), 海 (hài).

1. Sub-time: (23 o'clock to 01 o'clock).

2. Ugly time: (01 o'clock to 03 o'clock).

3. Yin: (03 o'clock to 05 o'clock).

4. Mao time: (05 o'clock to 07 o'clock).

5. Hour: (07 to 09 o'clock).

6. Time: (09 to 11 o'clock).

7. Noon: (11 a.m. to 13 p.m.).

8. No time: (13 o'clock to 15 o'clock).

9. Shen time: (15 o'clock to 17 o'clock).

10. Unitary time: (17 o'clock to 19 o'clock).

11. Time: (19 o'clock to 21 o'clock).

12. Hai time: (21 o'clock to 23 o'clock).

(1000 A + 100 B + 10 C + D) * 9 = 1000 D + 100 C + 10 B + A.

8999 A + 890 B = 10 C + 991 D.

Because A, B, C, D*9=D, C, B, A.

So we know that A=1;Ding = 9

Substituting 8999 A + 890 B = 10 C + 991 Ding 8999 + 890 B = 10 C + 8919

C = 89 B + 8

Because A, B, C, and D are all numbers from 0 to 9.

So B=0;C = 8

A, B, C, D=1089, multiplied by 9, to get 9801=d, c, b, a=1

B = 0 C = 8 D = 9

A = 1 because multiplying by 9 does not get to 5 digits.

Ding = 9 because 9x9 = 81

B = 0 because there is no carrying.

C = 8 because 9x8 + 8 = 80 satisfies B = 0

1089x9=9801

This is the heavenly stem, A, B, C, D, E, G, G, XIN, NON, and DEC.

Meaning: A: Like a grass forest breaking the ground and sprouting, the yang is wrapped in the yin. It is also believed that the armor of the armor also breaks through the armor of all things and stands out.

Ren: Pregnancy, Yang Qi lurks in the ground, and all things are pregnant.

癸: Suddenly, all things are hidden, pregnant and underground, and bright buds.

Origin: In 2697 B.C., when the Yellow Emperor, the ancestor of China, founded the country, he ordered the Daluo clan to explore the qi of heaven and earth, ** the five elements (gold, wood, water, fire and earth), starting with A, B, C, D, E, G, XIN, NON, and other ten heavenly stems, and Zi, Chou, Yin, Mao, Chen, Si, Wu, Wei, Shen, You, Xu, Hai and other twelve earth branches, which cooperate with each other into sixty Jiazi for the symbol of the calendar.

The Chinese calendar takes the time (days) for the moon to circle the earth as a month, and the time for the earth to circle the sun (days) as a year, and sets a leap month in order to make the average number of days in a year match the number of days in the return year. It is recorded that in the sixth century B.C., China began to use the nineteen-year seven-leap month method to coordinate the lunar and solar calendars. The sexagenary branch is a symbol set up by the ancients when they built the calendar in order to facilitate the 60 entry mode.

For the ancient Chinese, the existence of the heavenly stem branch was as simple as Arabic numerals, and later began to use these symbols on the lease map, orientation and time (time axis and space axis), so these numbers were given more and more meanings.

The ancients (one said the Yellow Emperor) observed the synodic moon and found that the concept of two synodic months is about 59 days. The 12 synodic months were roughly 354 days (similar in length to a return year), which led to the idea that the year had 12 months. In conjunction with the diary method (ten days of drying), the production of disadvantageous potatoes is like the birth of a lunisolar calendar, and the development of the heavenly and terrestrial branches appears; When it is more mature, it should be in the Xia, Shang, and Zhou dynasties.

In the ancient Chinese calendar, A, B, C, D, E, G, G, XIN, NON, and 癸 were called the "Ten Heavenly Stems", and Zi, Chou, Yin, Mao, Chen, Si, Wu, Wei, Shen, You, Xu, and Hai were called the "Twelve Earthly Branches". The two cooperate with each other in a fixed order to form the Ganzhi Discipline Law. Judging from the oracle bone inscriptions unearthed in Yinxu, the sexagenary branch was mainly used for the day in ancient China, and was also used to record the month, the year, and the time.

2 lyrics. Zheng) Rainbow persuaded the rain to cry, and the child kicked out the water droplets, shining the eyes of the lovers on the street.

Xu) In the ordinary alley, who is humming a song softly in an ordinary person's house.

Zhang) I don't know if you were happy yesterday's lover, I still remember to guess your expression.

Together) a rare good mood, suddenly sunny weather.

Zheng) as if love could appear at any time, as if every face was pleasing to the eye.

It seems that everyone has two childhoods, as if they are willing to do what they do.

Zhang) We are just Lu Lu Zhaozhen people A, B, C, D, in this flower world collective game.

He) rare good weather, why don't you salute me and I salute you.

It's rare to be in a good mood, the whole city is happy and happy, and passers-by are A, B, C, D.

Zhang) Sky changes into new clothes every day to please the hearts of the world, and today is really a sign of affection.

Zheng) throws a coin in the wishing pool, each of which is a message of love.

Xu) There are familiar memories in the eyes of strangers, understanding keeps us together.

The mind is clean and transparent, twinkling and shining.

The rainbow persuaded the rain to cry, and the child kicked out the water droplets, shining the eyes of the lovers on the street.

Zhang) In the ordinary alley, who is humming a song softly in an ordinary person's house.

I don't know if you were happy yesterday, but I still remember your expression.

Roll up your sleeves and walk and do passers-by.
