With the development of society and the improvement of living standards, many children are exposed to electronic products very early, and many parents directly give their children an electronic product to play by themselves. But are you worried that your child’s eyes can easily be hurt?

The most innocent time is the memory of 20 years of life on campus. At that time, we had no worries, no burdens, but also very naughty. It is the teacher who plays the role of father and mother, leading us to swim in the sea of knowledge, taught us a lot of how to be a man, accompanied us through a carefree day. At that time, we were really happy. Thank you for your teachers.

In the past two years, paperless office has become a new favorite of technology applications, from electronic contracts without physical objects to various writing reform hardware.

I think everyone should have used the kind of magnetic drawing board in their childhood. After writing the words, drawing the paintings, and pushing the magic plastic "eraser", nothing will happen. However, the original magnetic artboard, the resolution is really too low, and must be used with a magnetic pen, now it can only be nostalgic.
