In recent years, with the acceleration of urban and rural industrialization in Zhongshan City, many geographical units of towns (streets) have been formed. Hundreds of similar producers from huge industrial clusters have gathered together to form many hardware and gun locks. Furniture, food and other "one town, one product" regional traditional characteristic industrial cluster.

        After decades of development, Xiaolan Town has become one of the pillar industries with nearly 300 lock manufacturers. In the process of the development of industrial clusters, due to the considerable number of industry product standards or backward industry standards, and the large number of manufacturers, the industrialization of homogeneous cable locks with a small degree of homogeneity has restricted the development speed of the lock industry. Speed up the adjustment of the industrial structure and raise the bottleneck.
