FAQ (Frequently Asked Questions) for Chrono Acupuncture (Zi Wu Liu Zhu)
Q1. What are the Meridians Systems in Acupuncture?
The Meridian Systems of Acupuncture and Moxibustion originated from China have more than 4000-5000 years of history. Many basic theories concerning the internal organs, meridians, acupoints, and the use of acupuncture needles were recorded in Huangdi Neijing Suwen (the Plain Questions of Huangdi's Internal Classic) and Lingsu (Miraculous Pivot), the two earliest Chinese Medical books about Traditional Chinese Medicine.
There are 20 meridians in total in Traditional Chinese Medicine (TCM), Acupuncture and Moxibustion:
(1) The Twelve Primary Hand-Foot Meridians, including Liver (Liv), Heart (H), Spleen (Sp), Lung (L), Kidney (K), Triple Energizer or Sanjiao (TE or SJ); Gallbladder (G), Small Intestine (SI), Stomach (S), Large Intestine (LI), Bladder (B) and Pericardium (P). Liver (Liv) and Gallbladder (G), Heart (H) and Small Intestine (SI), Spleen (Sp) and Stomach (S), Lung (L) and Large Intestine (LI), Kidney (K)and Bladder (B), Triple Energizer (TE) and Pericardium (P) are related each other as the Interior and Exterior, e.g. Liver (Liv) is the Interior while Gallbladder (G) is the Exterior. The acupoints in Liver (Liv) Meridian are used for liver and/or gallbladder problems, and the acupoints in Gallbladder (G) Meridian may be used for gallbladder and/or liver problem both.
There are 309 acupoints totally on the 12 Primary Hand-Foot Meridians: 14 on Liv Mer., 44 on G Mer., 9 on H Mer., 19 on SI Mer., 21 on Sp Mer., 45 on S Mer., 11 on L Mer., 20 on LI Mer., 27 on K Mer., 67 on B Mer., 23 on TE Mer., 9 on P Mer. For both side of the body, it's 618 in total.
(2) The Eight Extra Meridians, including Governor Vessel (Dumai, GV, DM), Conception Vessel (Ranmai, CV, RM), Chong Vessel (Chongmai, ChV), Belt Vessel (Daimai, BV), Yin Heel Vessel (Yinqiaomai, Yin HV), Yang Heel Vessel (Yangqiaomai, Yang HV), Yin Link Vessel (Yinweimai, Ying LV) and Yang Link Vessel (Yangweimai, Ying LV).
Most health professionals use the 14 Primary Meridians: the 12 Primary Hand-Foot Meridians plus Governor Vessel (Dumai, GV, DM), Conception Vessel (Ranmai, CV, RM).
There are 28 points on GV (DM) and 24 on CV (RM). In total there are 361 or 670 in both sides of the body on the Standard 14 Primary Meridians.
The Eight Hui Points used in MNEF System are on the 12 Primary Hand-Foot Meridians but connected to the Eight Extra Meridians.
Q2. What is the Midnight-Noon Ebb-Flow (MNEF), or Zi Wu Liu Zhu Acupuncture? How Many Studies of MNEF Are There in Traditional Chinese Medicine (TCM)?
The Midnight-Noon Ebb-Flow (MNEF), or Zi Wu Liu Zhu in Chinese, is an ancient acupuncture theory of selecting acupoints. According to this theory, the acupoints from the Primary Meridians are related to the changes of the days and the hours in terms of the Heavenly Stems and Earthly Branches in Chinese Calendar. Similar to the tides, we can predict the status of the Ebb and Flow of Qi and Blood along the Meridians, so as to select the appropriate.
Practically, there are 3 MNEF Systems practically:
(1) Na Jia Fa or Na Gan Fa, The Day-Prescription of Acupoints Techniques for select the points on the 12 Primary Meridians in accord with the day to match the Heavenly Stems and Earthly Branches in the Chinese calendar.
The Five Shu Acupoints are used in this system and are in the 12 Primary Meridians and have considerable therapeutic significance on the limbs distal to the elbow and the knee. The Five Shu points are related to Five Interior Organs -- the Liver, Heart, Spleen, Lung, and Kidney on each of the 12 Primary Meridians. So there are 60 Shu Acupoints in total.
*NOTE: There are 60 Shu Acupoints in total, but there may be slight differences for which points from different studies and books in TCM are used. In Dr. Wu' Practical MNEF Acupoint Calendar, you may find that 2-3 Shu Acupoints are not listed, and 2-3 Acupoints listed.
For example, H3 and SI 2 are not listed because these two Shu points are used beyond the hours of 6 am to 11 pm. For practical purposes, only 6 am to 11 pm are listed. G40, SI4 and S42 are not Shu Acupoints in many books, but listed in the Calendar because some Chinese doctors and TMC studies have used these points as Shu Acupoints for many years and have successful results.
(2) Ling (Nin) Gui Ba Fa , The Eight Magic Turtle Techniques ( also called Extra Meridians Na Jia Fa. To select the points on the 8 Extra Meridians in accord with the day to match the Heavenly Stems and Earthly Branches in the Chinese calendar -- just use the 8 acupoints on the 12 Primary .
What does the name "Eight Magic Turtle Techniques" mean? These techniques use 8 Extra Meridians, 8 Hui Acupoints which match to 8 Divination Symbols (Bagua, or Pagua, or Pakua) -- Taiji (Taichi) Yin-Yang Symbol is in the center of Bagua from Taoism. Bagua was named from the great book of I Ching -- the Book of Changes, and said to be born on the Magic Turtle's back at the dawn of time. A detailed Bagua Chart is used as the map of Feng Shui for direction, and to remedy the problems in your body, your home, office, and aid your health and all situations in your life.
The difference between Na Jia Fa and the Eight Magic Turtle Techniques is that the Eight Magic Turtle points are on the 8 Extra Meridians but connected to the 12 Primary Meridians; and there are just 8 Hui Acupoints totally in this system.
(3) Fei Teng Ba Fa, or Ling Gui Fei Teng, and The Eight Magic Turtle Flying Techniques are very similar to (2), but only use Heavenly Stems to do calculation. Most of the studies and books consider them together. Many medical books and dictionaries don't know the difference between them. Both use the Eight Hui Acupoints, but the calculations have some differences.
Dr. Wu's Practical MNEF Acupoint Calendar combines Three Techniques together. It uses The Eight Magic Turtle Techniques (Ling Gui Ba Fa) mainly but also lists the acupoints from The Eight Magic Turtle Flying Techniques (Fei Teng Ba Fa) and The Day-Prescription of Acupoints Techniques (Na Jia Fa). It lists all 8-Hui Converging Acupoints (# 1 to # 9) from Ling Gui Ba Fa and Fei Teng Ba Fa as the First Choice, and all 60 Shu Acupoints (60 )* from Na Jia Fa as the Secondary Choice.
In Dr. Wu's MNEF Calendar: It's normally to select the "8-Hui" Acupoints firstly according to "Nin Gui Ba Fa" and Fei Teng Ba Fa (shown in the First one or two of each calendar hour by numbers); then secondly, if necessary, according to "Na Jia Fa" (shown after a slash of each calendar hour by letters & numbers). For example, in 03/06/2003, 8-9 pm, the acupoints shown in the calendar are: "S:8,6/B65-S42". S = Stomach Mer., #8 is from Nin Gui Ba Fa, #6 is from Fei Teng Ba Fe, B65-S42 is from Na Jia Fa.
Q3. What are The Eight Hui Points in Acupuncture?
There are eight important strategic Acupuncture or Acupressure points related to the physiological function of organs, meridians or certain areas of the human body. The Eight Extra Acupuncture Meridians are connected to these eight "8-Hui" Converging Acupoints separately on eight regular meridians -- 8 of the 12 Primary Acupuncture Meridians. That means that the Primary Meridian System AND the Eight Extra-Meridians Converge in these Eight Hui Points. Administering acupuncture or acupressure BOTH systems.
These "8-Hui" Converging Acupoints are:
# 1 = B62 (Shenmai) in Bladder Acupuncture Mer. (B);
# 2 & # 5 = K6 (Zhaohai) in Kidney Acupuncture Mer. (K);
# 3 = TE5 (Waiguan) in Triple Energizer (Sanjiao) Acupuncture Mer. (TE or SJ);
# 4 = G41 (Foot-Linqi) in Gallbladder Acupuncture Mer. (G);
# 6 = Sp4 (Gongsun) in Spleen Acupuncture Mer. (Sp);
# 7 = SI 3 (Houxi) in Small Intestine Acupuncture Mer. (SI);
# 8 = P6 (Neiguan) in Pericardium Acupuncture Mer. (P);
# 9 = L7 (Lieque) in Lung Acupuncture Mer. (L).
If you don't know where these points are located, please Click on the desired point above and go to a detail graphic.
There are TWO kinds of "8-Hui" points in Acupuncture and Traditional Chinese Medicine (TCM): The Eight Hui Influential Points and The Eight Hui Converging Points. Do not confuse them. Hui has two meanings in Chinese (Hui is presented for 4 different Chinese characters at least actually): Influential of Focal and Converging.
The Eight Hui Influential Points is the 8 Hui (Influential of Focal) Points. These are 8 important acupoints related to physiological functions of internal organs or tissues. 8 different points are used: 1. CV17 (Tangzhong) -- Focus of Qi, 2. B17 (Geshu) -- Focus of Blood, 3. B11 (Dachu) -- Focus of Bones, 4. G34 (Yanglingquan) -- Focus of Ligaments & Muscles, 5. G39 (Xuanzhong) -- Focus of Marrow, 6. L9 (Taiyuan) -- Focus of Pulses, 7. Liv13 (Zhangmen) -- Focus of Solid Organs, 8. CV12 (Zhongwan) -- Focus of Hollow Organs.
Why is there #9 point here? There are just 8 Hui points in total. The numbers for the points are from the Bagua -- the source of The Eight Magic Turtle Acupuncture Techniques. In the bagua diagram, there are eight areas, or "guas," encircling the center, 8+1=9. These nine different zones correspond to nine major numbers of life. To calculate the opened acupoints for a certain date in a certain hour in Chinese Calendar (Not in Western Calendar!), the ancient Chinese doctors used 9 numbers, matched to these 9 Zodiac Zones, to stand for 9 locations in the human body. Each point in 8-Hui is related to one number, but one point (K6) is related to two numbers.
is the difference between the Chinese and Western Calendar?
The Western calendar (the Gregorian Calendar)
is a Solar calendar based on the earth turning around the
Chinese calendar is primarily a Lunar calendar based on the moon turning around the earth.
It's actually a Lunisolar Calendar. Unlike the Greek or Islamic
Lunar calendar, the MONTHS in the Chinese calendar are based
on the moon ; but the YEAR in the Chinese calendar is based
on the sun. It uses Intercalary months -- add one more month
in an Intercalary year, then there were 13 months in this
year. There are always either 29 or 30 days per month, no
matter if it's an Intercalary month or not in the Chinese
Calendar. To adjust the difference -- add 1 Intercalary month
every 3 years, add 2 Intercalary months every 5 years, and
add 7 Intercalary months every 19 years. It seems complicated
but not if we remember that we also use Intercalary days in
the Western calendar. That's the reason why in February there
are 28 days but 29 days every fourth year. During a period
of 400 years 97 (no 100) intercalary days would actually be
added in total.
Chinese calendar uses the terms of the Heavenly
Stems and Earthly Branches, and
the combinations of 10 Heavenly Stems and 12 Earthly Branches
to present the years, days and hours, e.g. Jia-Wu Year, Jia-Wu
10 Heavenly Stems are: 1. Jia 2. Yi 3. Bing 4. Ding 5. Wu* 6. Ji 7. Geng 8. Xin 9.Ren 10. Gei
12 Earthly Branches are: 1.
Zi 2. Chou 3. Yin 4. Mao 5. Chen 6. Si 7. Wu* 8. Wei 9. Shen
10. You 11. Xu 12. Hai
*Wu is presented as 4 different Chinese characters at least because
there are 4 tone marks for each syllable.
There is no way to show 4 tone marks for each Chinese syllable
in English so far. Therefore, at times it causes much confusion.
Wu in 10 Heavenly Stems, Wu in 12 Earthly Branches, Wu in
numbers (means 5) and Wu in Dr. Wu are 4 different
Chinese characters. For years: use only one Heavenly Stem plus one Earthly Branch,
For months: uses numbers 1 to 12 like in Western calendar;
For dates and days: uses numbers 1 to 30 for dates and uses one Heavenly Stem plus one Earthly Branch for
days, e.g. March 6 (date), Wu-Yin
day; (There are No days like Monday
to Sunday in Chinese calendar.)
For hours: uses 12
Earthly Branches to stand for 12 periods (called
Shi-Chen) during 24 hours, each consisting of 2 hours;
Q6. What are Nomenclature,

Q7. Can The MNEF-Eight Hui Acupoint System take place the Primary
Yes and Not.
Yes, because the MNEF System may cover most
of the problems already. If you are not a health professional,
Not, because the 14 Primary Meridians are still
the basic system used by most health professionals today.
For some cases, you need to combine the MNEF-Eight Hui Acupoint
System with the 14 Primary Meridians System, and your patients'
symptoms. For a health professional, you need to learn more,but
MNEF System is a good beginning for easy practicing.
Q8. Do I need to consider different Time Zones?
It's Not necessary in the US.
The Biological Clock in your body follows the local
time no matter what Time Zone it is. The Time Zones
used in the US are already follow the turning around of the
Earth scientifically. We already use a 3 Hour Time
Zone difference for the whole country in the US.
It's about 45th Meridian degrees across the
West coast and the East coast of the US. That's about 3 hours
in natural time difference because the 15th Meridian
degrees is equal to 1 hour difference by the Earth's
You just need to consider in a few special
(1) You travel from one place
to another. For a few hours to a few days, if you still have
Time-Zone Reaction or sickness -- That means your Biological
Clock does not fit the local time yet, it's better that you
follow the old Time Zone.
(2) In some countries, e.g.
China, there is not Time Zone used. All the
areas in the whole country use the standard Beijing Time.
You may need to adjust (plus or minus) the Standard Time to your Local Time.
Check a standard map and figure out how many Meridian
degrees difference between your
home location and Beijing (or the Standard Time location).
For example, The Meridian degree in a city west to Beijing minus the degree in Beijing is equal to 14. 15th
Meridian degrees is equal to 1 hour. 14/15 x 60 = 56 minutes,
about 1 hour early -- minus one hour to your
calendar hours. You may disregard Time Zone if it's less than
one hour because the acupoints are the same in a 2-hours
