If you are a human, you are surely aware of the traffic light signals. You must also be aware that it is necessary to stop at the red signal and proceeds on the green. But why do you need of doing so, you do this because you are a human being, and traffic signals are generally made for humans only, as you might have heard. But have you ever heard that traffic signals are also made for animals, especially for camels? Probably not, but what doesn't happen anywhere that happens in China. Yes, a traffic signal has been installed for camels at the Mingsha Mountain and Crescent Spring in Dunhuang City to avoid collisions between camels and the people there. It is claimed to be the world's first traffic light signal for camels. The whole concept works on a very simple strategy, as soon as a green signal appears in the traffic lights, the camels go ahead, and whenever a red signal appears, the tourists who visit the area, move ahead. What an amazing idea it really seems to be.
