1. Two-layer glass doors with heater: Ensure that the two-layer glass doors have good insulation to reduce heat transfer. Consider adding switchable heaters to reduce condensation on the doors and maintain the clarity of the glass.

2. Adjustable shelves: Provide adjustable shelves to increase the flexibility inside the refrigerator, allowing users to adjust the height and position of shelves as needed to accommodate different-sized food and containers.

3. Imported compressor: Use a high-quality imported compressor to improve refrigeration and freezing performance while reducing energy consumption. Ensure the compressor operates efficiently to extend the refrigerator’s lifespan.

4. LED lighting on the door frame: Use LED lighting on the door frame to provide bright and energy-efficient illumination, enhancing user visibility and making it easy for them to find the items they need.
