I suppose buzhuoli would be “not focused.” I’ve come across examples that compare zhuoli lianxi “focused practice” with buzhuoli lianxi (unfocused practice). It has to do with how and where to concentrate one’s effort.
An “ignition point” is zhuohuodian, so zhoulidian is the point of application of force, or of effort. As I noted, the most current usage seems to be the idea of collective or collaborative effort.
Some further rambling thoughts: To me, there is not really an issue of physical strength (li) vs. intention (yi). Or to put it another way, there should be no conflict or dichotomy of strength vs. consciousness, or outer vs. inner. When I think of focusing intent, it has fundamentally to do with action. One could say that Taijiquan practice is an exercise in what the Ming philosopher Wang Yangming called “the unity of knowing and acting” (zhixing heyi). Tu Wei-Ming wrote of Wang’s conception of zhixing heyi:
“For to know, Yang-ming suggested, is not to assimilate a set of externalized values, but to manifest what one has truly understood in concrete actions. It is a delusion to believe that the quest of knowledge can be independent of its application. If one studies the words of the sages as if they had nothing to do with one’s body and mind, here and now, one inevitably falls prey to self deception. The words of the sages are to be learned in experience. They can never be fully internalized by a process of cognitive appreciation. Real experiential participation is so much an integral part of the learning process that to delay action means to falsify knowledge.”

Sometimes I need to cast the net wide in order to sharpen my own focus. Knowing your appreciation for the detective work of Judge Dee, you probably know what I mean. So that’s why I like to go off on tangents about the context and meaning of “zhuolidian” in a taijiquan manual written by Fu Zhongwen and edited by Gu Liuxin, published in 1963. I’m glad you brought it to my attention!
