The Chinese word "不拘小节" is formed by sequentially combining the characters "不" meaning "not", "拘" meaning "to restrain", "小" meaning "small", and "节" meaning "details" or "trifles", creating a literal meaning of "not restraining small details". It originates as a fixed expression from classical Chinese texts, notably the "Book of Later Han", where it is used to denote the trait of ignoring minor matters. The phrase's formation relies on this specific character order to convey the idiomatic sense of not being concerned with trivialities.
