This is the lineage maintained by Grandmasters Helen Wu (current lineage holder) and Simon Hu (her husband).
I have few and far between met people like these. There is a wealth of knowledge here unsurpassed by anyone else I have ever met. What follows here are some notes I've pulled together about the lineage itself and what it contains. Of course not everyone can learn everything, but it is interesting to get a glimpse of what Wu Yi Jie He has to offer.
Between Wang Ziping and Madame Wang they meet many Masters and were good friends. The wealth of knowledge and information that were passed on is awe inspiring for me.
For example, included among those who Madam Wang's daughters learned Taijiquan from (besides Madam Wang) are Gu Luxing, Fu Zhongwen, Ma Yuehliang, and Wu Yinghua. In addition, Madam Wang was friends with Sun Jianyun. Wang Ziping was friends with Sun Lutang, historian Yang Chengfu was associated with it. There was a lot of sharing of information.
Primarily 20 postures for health and longevity, modified to 24 postures by adding on four important moves and a transition move. This is the primary form of qigong promoted by the schoool.
Additionally there are many other forms of qigong and daoyin available. Such as;
System specific weapons are usually tai chi sword and flying rainbow tai chi fan. There are others such as a flying rainbow bagua fan, dual fans, and others. There are also partner exercises and two person sets.
One of the gems of this is the understanding of single movement practice related to any posture in the system. I've see repeatable small sets of 1 or 2 moves which one may repeat over and over pulled out of or constructed from a litany of forms. This is truly a hidden gem of this system.
10 to 20 forms of Tantui IIRC.
Sun style and Chen style. Yang style is limited to 24 postures and associated qigong styles. Also teaches push hands and applications on some occasions.
'Old' Hebei Xingyiquan including five elements and 10 to 12 animals, as well as continuous form and other material.
At least one form. The movements are quick, swift and powerful. There is a hidden energy in the movements which is extremely crisp and direct. I have not seen a similar performance except in Xingyiquan and Chen Style.
Hua Quan is a variant of Longfist, but this description does not do it justice. It is a huge style containing a catalog of forms from many other styles, which have been reorganized into a single system. It is on one hand unique while being a catalog of a litany of other styles, each retaining it's own unique flavor. I have heard that there may be close to 100 forms in Hua Quan.
Although Bagua is not one of the items Madam Wang ever really attributed to her father, her daughters trained with her, with her father as much as they could (the Cultural Revolution prevented a lot of things from happening) and then trained with family friends and acquaintances.
So while it is not certain that Wang Ziping knew bagua, what we do know is that he had many friends and some were Masters of bagua.
Madame Wang was also talented in bagua and I believe they knew at least 3 bagua full systems: linking palms, old bagua palm and swimmining dragon – not to mention their own system (which included at least a 'bagua' flying rainbow fan – a bagua fan that has not been demoed or taught to my knowledge.)
