Social networking Facebook is also somewhat beneficial for all of us, but it also brings harm to us. The advantage is to provide insight into information you don't know, such as information on how to cook, how to work more smoothly for the company, and all have different meanings. In contrast, Facebook brings unpredictable harms to us, such as watching bad and vulgar programs, fighting outside school societies, etc. In short, facebook comes back and gives us the information we need. Everyone remember to find good information for yourself and not find bad information for yourself
