In the beginning, I want to express my apprication to Serlina providing us the meaningful & moving song. After watching the video, something inspires me leading me to have a deep thought on the discrimination problem. A  number of factors could account for this phenomenon. One possible reason is the traditional thought on people's mind which is hard to change. Because  the original thought by the elder people infuence the young, as a result, a part of us are unaware of having the prejudice on the black people. Another cause is the history of the black man & the white man.
