寧方毋圓
In a concert hall, a portrait of a local lady by a well known artist I have read many times and then, noticed this 寧方毋圓 principle. I pondered over the reason is that he keeps all details in relatively one focal point in an impressionistic style.
It is also can be extended to connect with other ideas in various activities. In Chinese square character it becomes a rule which has lasted thousands of years, which might need a reform that was long overdue.
