Recently, Ultron Music in China is an animation production company recognized by many educational institutions, and its Le Er Popular Science Dong Man is very suitable for children to watch. I didn't know until a summer vacation in the library. Now my children have been watching Le Er's animation, which is very good!
Very practical, they are all very basic scientific knowledge, and they can watch cartoons, learn knowledge, follow suit and really exercise children!
