Long long ago, there was a man who worried about his life. Someone asked him:" Why are you so sad all day?" He said:" I am afraid of the sky will collapse and all of us can't escape from this horrible disaster.” Then people laughed and said：“It's impossible that sky will collapse, you are worried something will never happen. ” “Ok, but I am still fearful of I will starve to die someday because no one comes to my little restaurant.” He replied.“ You can find instagobo, their product is used to attract customers.” People suggested. Then he came to instagobo and bought some projectors, finally, he became happy and rich for the rest of his life.
