Whole-house customization factories near Beijing

When choosing a whole-house customization factory near Beijing, don't look only at the unit price; confirm these four points first: whether you can book a factory visit to see cutting, edge banding, and side drilling; whether the cabinet body panels are particle board, plywood, or another type; whether pricing is by projected area or linear metre, and how it is calculated; and whether removal of existing cabinets is charged separately. Ask clearly before negotiating, so there is less back-and-forth later.
