"Cluster registration" implies a plurality of enterprises register their domiciles with the address of the same enterprise, which will provide hosting service to others, to achieve office space sharing.

Zhongshan attempted to implement domicile registration reforms in April 2018, one of which was the trial of "cluster registration".

Dao'er Cluster Registration and Hosting (Zhongshan) Co Ltd successfully obtained a business license in Torch Development Zone in August 2018 and became the first enterprise in Zhongshan to provide residential hosting services for cluster-registered enterprises. Since its establishment, Dao'er has attracted nearly 700 enterprises to settle in it.

Dao'er is situated in Zhongshan Datang Incubator Co Ltd. The company provides services to a lot of enterprises in such areas as information technology, lighting supplies, building materials and bathroom accessories and e-commerce.

According to a staff in charge of Datang Incubator, in addition to providing company registration and address hosting, the cluster registration and hosting mode also includes a series of services such as bookkeeping and intellectual property agency. The company also incubates a few excellent start-ups each year to help them grow in strength.
