There are so many problems around us, with the high-speed development on the internet, our planet becomes a global village, we have the benefit to know all these problems clearly and instantly. In my imagination, a robot – ‘Mr. STOP’ could stop all these problems immediately, so that we could have a better world for generations. Of course, it is just a dream, ‘Mr. STOP’ tries to highlight all these problems to raise public awareness, to remind people of their responsibility for this mother earth.
