What is the good earth home? "Smart Witness" LED micro video shows us a city of wisdom. This is a warm and sweet comic short film. The 5-year-old Peas live in the city of wisdom with Mom and Dad. Dad’s office, mother’s kitchen and cars on the road make her feel amazing and pleasant.
In the office, Dad only needs to tap and play on the glowing table to do a lot of work. Mother only needs to press it gently in the kitchen cabinet, and the delicious moment is released. The street light is aware that the car will open automatically when it approaches, and the unmanned car will go home by itself at night. The most amazing thing is that all the work is done with a little power!
The tender children, the picture of happiness, melt our hearts little by little. For such a wonderful city of wisdom, we have no time to think about it, and look forward to it coming soon!
Less consumption of one degree of electricity, more restore a minute of green!
