Abstract “Ju” is an interactional process including stated objective and multi-subjects, which also can be comprehended as a whole chain of events. Based on social interaction perspective, the stakeholders arrange their interaction actions according to the purpose of Ju. The direction of interaction is the tendency of Ju. The state of interaction in a short time is the situation of Ju. The dynamic mechanism of Ju which is formed by an intentional action is different from the dynamic mechanism of Ju which is natural evolution. In the light of the strength people get resources and maintain relations in social interaction, Ju can be divided into four types. Based on events system theory, Ju can be interpreted as the evolution process of events chain. The characteristic of events influences the tendency and situation of Ju. The relationship between events can be viewed as the action feedback after the stakeholders interpreting the information. The value judgment standard of events characteristics comes from two perspectives. One is the goal orientation of the stakeholders. The other one is the subject features of Ju. The influence of personal orientation and Ju orientation on events judgement are the important reasons of the changed tendency of Ju.
