To better manage labor, costs, and project specialization, we have set up satellite factories in Guangzhou, Shenzhen, and Huizhou, in addition to our main facility in Dongguan. Each location focuses on different product lines — for example, leather goods are typically produced in Guangzhou, luggage items in Huizhou, and backpacks are primarily handled in our Dongguan factory.
