This diagram will draw 47 lines of the meridians and collaterals including twelve meridians, twelve divergent collaterals, fifteen collaterals and eight extra meridians in the same human body diagram, it shows distribution of the whole body surface of 47 meridians and collaterals how to intersect, encounter, connect and combine and relation between acupoints and distribution of the above meridians and collaterals.

Distribution diagram of lines of twelve meridians, twelve divergent collaterals, fifteen collaterals and eight extra meridians are drawn separately from of old, and each diagram is out of picture, distribution relations between these meridians and collaterals and encountering contents with acupoints are hardly seen, such as there are 15 meridian and collateral distribution lines in addition to branches covered densely on face, what is the distribution relation of these meridian and collateral lines and what is the relation between meridian and collateral lines and acupoints, there is no overall analysis yet. Yang heel vessel, yang link vessel and gallbladder meridian are distributed in side, there is no diagram to inquire about how they range. We do not know how do yin heel vessel, yin link vessel, kidney gallbladder meridian, spleen meridian of foot-taiyin and liver meridian of foot-jueyin distribute in medial aspect of lower limb, there is no expression of distribution of some divergent collateral s and collaterals and their assembling. How do Shanzhong acupoint encounter conception vessel, spleen meridian , kidney meridian and meridian of hand-shaoyang, if such problems are not solved, there is difficult to explain relation between meridians and collaterals of body surface and relation between acupoints and meridians and collaterals. There is lack of data which is related to meridian and collateral and acupoints in science study. Clinically functions of acupoints are not applied roundly.

Researching where all meridians and collaterals of acupoints start, encounter, intersect and diagram of the connecting lines of the meridians and acupoints, this diagram is drawn on the basis of twelve meridians, twelve divergent collaterals and fifteen collaterals in Illustration of Meridians and Collaterals. This diagram only shows body surface lines of meridian and collateral, it does not include lines that come out of splanchnocoel; it does not show distribution lines that enter into splanchnocoel, brain, and nasopharynx and collateral branches that are associated with meridians in internal and external relation.

Diagram of connecting lines of meridian and acupoint is different from diagram of meridian and collateral. Drawing of diagram of meridian and collateral gives priority to Miraculous Pivot, meridians and collaterals and mainly shows relation between meridian and collateral and internal organs. Meridian and acupoint takes acupoint as theme and draws according to distribution of meridian and collateral, it mainly shows acupoints of meridian and collateral. Therefore there are differences in two diagrams. There is no zigzag of meridian and collateral line of right angle in diagram of meridian and collateral. Diagram of meridian and acupoint appears many zigzags of right angle. This diagram almost folds distribution of two diagrams. An important problem should be defecated here, at present it is incorrect that many "scholars" takes diagram of connecting lines of meridian and collateral and acupoints which belongs to fourteen meridians as flowing route of fourteen meridian and vessels. It is known that flowing route of meridian and vessel is not at surface skin but between "Fenrou points". Three hundred and sixty five acupoints of human body is the distribution center of three hundred and sixty five collaterals on skin which diverges from meridian and collateral trunk (see illustration of three hundred and sixty five collaterals). 

Distribution of three hundred and sixty five collaterals is quite wide on skin; it becomes fourteen skin areas (see illustration of fourteen skin areas) but not a line. It is in order to show acupoints on meridian and collateral that appears connecting lines of meridian and collateral and acupoints. In fact, connecting lines of meridian and collateral and acupoints what is affiliated with meridians and collaterals of acupoint is a distribution diagram of meridian and collateral and acupoints but not meridian and collateral diagram. In ancient books such as Illustrated Manual on the Points for Acupuncture and Moxibustion as Found on the Bronze Figure, Yizongjinjian arrange diagrams separately on diagram of meridian and collateral and diagram of connecting line of meridian acupoint. Therefore, this diagram improves places of right angle on connecting line of meridian acupoint; some draw right angle lines as camber. Some draw on branch of collateral vessel, such as Lieque acupoint and Fenglong acupoint are acupoints of collateral vessel, but some diagrams of meridian acupoint force right angles to zigzag and appear many illogical lines. This illustration rehabilitates them to collaterals.

Problems of converging acupoints deal with 5 types. The first type is crossing acupoint which plays orientation role in circulations of meridian and collateral, such as meridian of hand-taiyang, meridian of foot-taiyang, yang link vessel and yang heel vessel of Naoshu acupoint crosses. The second type is acupoint on deep part of meridian and collateral, such as Zhongji and Guanyuan acupoints are positions of conception vessel, kidney meridian, spleen meridian and liver meridian which float along abdomen line. Crossing of conception vessel, spleen meridian, kidney meridian, triple energizer meridian, lung meridian in Shanzhong acupoint are the same. The third type is acupoint on shallow part of meridian and collateral, such as converging acupoints on meridian of foot-taiyang, gallbladder meridian, yang heel vessel and yang link vessel of head which float along each other. The fourth type is congregation acupoints where many meridian lines assemble but not circulation part of meridian line. The fifth type is where parts cross, such as supraclaveicular fossa is a big part where meridian and collateral passes but not crosses.

There are records of crossing acupoints in books from ancient, but there is no agreement on certain acupoint assembling which meridian. Some think crosses two meridians and some three; this diagram adds some reasonable assembling meridians according to records in A-B Classic of Acupuncture and Moxibustion, circulation parts of meridian and collateral and acupoints that some experts record. No efforts will be spared to draw assembling meridians and collaterals on assembling acupoints and show real visage of meridian and collateral lines of body surface and connecting lines of acupoint.
