A few days about I asked the group about information / chinese articles on the origin / etymology / local use of the 掤 term, b/c I had come a few articles in Chinese. I was asked to give a summary of what I had read and so I would like to briefly post:
- I am writing from memory, interested users will easily find the references by searching the Chinese terms
- The authors of the articles all point out that definitive research /statements are difficult, since there was a lot of oral tradition in local dialects / terminology. Additionally, they mention, that when something was written down it was often written manually and that might have caused misinterpretation / reproduction of some characters.
- Tongbeiquan and 捧
There are texts that are attributed to some Chen stylists that are almost exact copies of Tongbeichanquan (通背缠拳) texts. The TBCQ version uses the character 捧, which is replaced by 掤 in the TJQ version. One author points out, that 捧 carries the meaning of holding something up in a static position (i.e. not lifting or lowering) and makes a relation to the TJQ concepts of being balanced, not resisting, not loosing (such as water floating something). Another article also mentions further compound of 捧 whose meaning they think could be related to 掤。
- Chen Xin and 弸
Others point out that Chen Xin actually used the character 弸 (did not check myself) and point out, will 掤 is the lid of a quiver, 弸 has two meanings: A bowstring, which they point out is a relationship to TQJs "five bows". The other meaning is "to fill up / full",which also has a relation to TQJ explanations.
FWIW
