Why production lines go 1-2-3-6 and skip 4 & 5

13-04-2026

Walk through any of factory's production facilities in Vietnam or China, and you will notice something unusual. Production lines are labeled 1, 2, 3, and 6. End-line quality control stations are numbered 1, 2, 3, and 6. Where are 4 and 5? In traditional Chinese manufacturing culture, the number 4 is avoided because it sounds like the word for "death." The number 5 follows close behind — associated with "nothing" or "delay."  So we skip to 6 — which sounds like "smooth"or "well-off." That is exactly how we want every polyester bag and leather bag production run to go. A small superstition? Maybe. But it is part of our identity as a leading bag manufacture with integrated China Vietnam factory operations. Every polyester bag that leaves our China Vietnam factory system carries this wish for smooth delivery and lasting satisfaction. We are proud to share this secret because it reflects our attention to detail, cultural respect, and commitment to quality.
