營 is composed of a variant of 榮 (torches) and a variant of 宮 (palace). 榮 is a pictograph of two torches, while 宮 refers to a residence. Thus, 營 conveys the idea of a residence illuminated by torches, indicating it is located outdoors and has lighting and guards at night, so 營 refers to a military encampment. A military encampment is extremely important and must be well managed and constructed.
