Live video streaming is a new form of network communication for the real-time interaction between network hostsand audiences. Its application has brought much convenience to people's study, work, and life, and hassimultaneously caused some phenomena against public order and good deeds. From the perspective ofepistemology, they are the consequences of human's cognitive fragmentation, superficiality, and human'suncontrolled self-discipline ability. In order to fundamentally reduce or avoid the occurrence of these socialproblems caused by live video streaming, the key points might be not only supervising and guiding live videostreaming in time, but also improving the participants', especially juveniles' abilities of rational judgment andself-discipline through providing them with specific publicity and education. In this aspect, the thoughts of"observing things by Heart" and "emotion dominated by rationality" in traditional Chinese culture can be fully usedto strengthen the assessment and governance of phenomena in live video streaming.
