After the installation of the packaging box is completed, users are not allowed to change the structure without authorization, dismantle bolt components, or add or reduce partition walls, as self modification may cause component damage. If changes are needed, it is recommended to consult and agree with the manufacturer before making changes. 

2. The packaging box houses are connected as a whole with steel structural components, and users arrange electrical lighting equipment. Wires cannot be directly tied to the steel structure, and should be isolated and installed with conduit or trunking to avoid electric shock. 

3. The light steel structural components of packaged houses should be maintained and painted once every 1-2 years to extend product life and maintain aesthetic appearance.
