As per the response from my earlier article, I would like to take the opportunity to write a bit more about the 鐵版神數 which seem interesting to everone here.
Another popular great old TCM master 朱雲山. In his book 《鐵版神數心得》, ( the book i have, can see from the photo), preface said:
序 preface
<鐵版神數> is like a heaven book of no words, regardless of a person has been mastering those i-ching, zi wei dou shu and others for long years, if without the guidance, advise and learning from the <鐵版神數> specialist master (sifu) , the person would still be unable to break into the core of <鐵版神數> for accurate operation, still like being an outsider, no matter been several ten years studies into it.
鐵版神數,就像一本無字天書,凡未蒙熟精此道者點竅、說明,欲自個兒閉戶造車,即使已有易卜、斗數等詣境,心血熬盡了,數十年歲月過去了,卻仍是一介門外漢! 
The attractive of it, apart from the phrases are written in classical poem style, it has the power on telling a person's family details such as parent born/death year, parent remarried/ divorce, number of brother sister, number of children, the person married remarried how many times, brothers and/or children capabilty, the person's death year, etc... So accurate that like had been closely living with the person. If this is being used properly, you could be able to make use of it for achieving.alot of things, showing off your magical power to people in everywhere. It might look simple in its methods, which relate to the yi xue eight trigrams where the Heavenly stems are being mapped to specific trigram (bua), Earthly branches are being mapped to specific trigram, daymaster is mapped to specific trigram, using Ho Lo (River map, Lo shu) methods to derive the relevant numbers....... selection and mapping of those trigrams, then converting the trigrams into numbers. These numbers could be brought down to lowest level coding for details. Ever said two persons of aame bazi might have different destiny, this is due to the birth time different, for the reason 鐵版神數 method has further divided one bazi hour (時辰) into 8 sections, and further into each section for which 15 minute slot, once the birth time at such details is set correct, then using the abacus to calculate as per the various relevant fotmula for computing a set of numbers giving to the person (client) to search as per the numbers in the destiny description book for relevant details.
鐵版神數引人入勝處,詞藻優美是的特色,尤能道出人之六親、運命、生死諸事,歷歷如繪,用之得法如虎添翼,足以炫世,究其八卦加則天干配卦、地支配卦、日主配卦、河洛配數、地支取數……無非循此配卦,再以卦取數世。此數甚精微,嘗謂八字同,而命有異者,乃時刻不同,故以一時推八刻,一刻又推十五分,時刻準確則命數悉合,至此在算盤上撥弄加減算出幾千幾百幾十幾,此數可授書由客人去翻閱。
The charming of 鐵版神數 since the ancient time to nowadays, has been increasing the popularity and reputation, especially among those high official people, politician, weath upper class people, entertainment movie and tv stars. Those wish to own the 鐵版神數 secret operating method, should not be too stuborn on taking the written formula poem wording meaning, as the proper way should be following your feel and sense at the time of the process. As a hint here, if you use 邵子 methods for deriving the numbers, you would be easily lost in the maze. Like a gold lock but noone could open it. 鐵板神數 has its own silver key, these.are kind of secret methods(eg encoding, decoding, etc) , once you know and own it,.you are powerful in everywhere.
鐵版神數魅力無窮,自古及今,盛譽益顯,達官貴人,影視紅星皆趨之若騖,希望擁有這套心法者,祈勿被詞意所困,如看無字天書,悟是非最佳途徑,神來之數隨意而發,從此通暢無阻矣!心得感言鐵版神數若用邵子數來求,卡在迷魂陣中,似一把金鎖,從無人能開啟。鐵板神數另有一把銀鑰,也祇有些微「心法」而已,有了它,夠您行遍天下。

In the search of one old TCM master (Zi Wei Yeung紫徵楊) who is famous in zi wei dou shu 紫微斗數, it has one live example of the destiny findings for a person once his/her birth hour into specific hour section and minute slot been set correctly.
3809 此刻生人,雙親俱全。born at this moment, you have dad and mother still alive living.
8689 分有前母,生我後母。 your dad has two wives, so you have two mothers, the second one gave birth of you.
6929 兄弟五人,同父不同母。you have five brothers, from same father but different mother
9767 妻命甲子生,姻緣注定。your wife was born in 甲子 year, your marriage is destinated.
8661 先女後男,數定不差。you have a daughter then follow with son.
5331 數有六子,四子送老。you have 6 sons, by the time you pass away, you have 4 sons making the funeral arrangement
7205 子多而貴,樂莫大焉。you have many sons, all are very capable having big achievement.
4534 慷慨熱心腸,為人無鄙吝。you are ver generous and passionate helping others, a righteous person.
7251 問名無成,問利有益 you dont have reputation achievements, but have achievements in business, money wealth.
3584 數注其人,四方為家。you are destinated for having a travelling life, everywhere can live and work
3035 經商異地,满載而歸。you in overseas are doing very successful business, make yourself very rich.
In his rseach, he saud, due to different school/lineage and also different master's specific coding methods for confidentiality, the birth hour section and minute slot of a person derived from Master A may be different from Master B.
Futhermore, the numbering methods used for each destiny description note can be different among those.masters.
各派大師再用密碼法不同而編號的批文也有所不同:
Below are three very famous and respectable TCM masters ( 吳師青, 馬翰如, 阮閒雲 ) also the 鐵版神數 high skilled masters in long old days though all had passed away at long time ago. Though the same number is used but for different destiny description, so mean each of them having their own coding and decoding.method.
For example,
Number: 90470 - Destiny description
(吳師青) 夫小五年 hubby is 5 years younger
(馬翰如) 母親何日逝,金水是歸期。mother pass away in year of metal or water.
(阮閒雲) 數有倫枯,妻帶微病。wife's health is often suffering from. small illness
..............................
From all these, you could imagine how mysterous is this TCM method, in order to keep its prime position in the TCM society circle, rumour has it, the master is alowed to teach and pass on this secretly to only one disciple ( some said, is within 5), never would be openly teaching in class.
