There is a famous saying: “when I first learned Zen mountains were mountains, and rivers were rivers. After I studied Zen, mountains were no longer mountains, and rivers were no longer rivers. After I finally understood Zen, mountains were mountains and rivers were rivers.”
It shows a circular pattern in thinking. That way is more the Chinese way of thinking, the advanced seems so basic. Yet the basics are so advanced.

Robert Chu studied with Hawkins Cheung (among others) and together with Rene Ritchie, he wrote a book back in 1998 called Complete Wing Chun: The Definitive Guide to Wing Chun’s History and Traditions.
This was one of the first books I bought back in my early training and it (if I recall correctly) did a pretty good job of explaining how Wing Chun became so diverse and they examined various lineages in a fair and balanced look.
Here is a video with Sifu Chu delving into a few of the basic techniques.
