We consider a general scheme to find a possible correlation in quantum systems from the information of only partial systems. As a natural but a powerful property, if the partial system is in a pure state, then we can conclude no correlation with any other environment. On the other hand, if the partial system is in a mixed state, any static property cannot be used to determine a possible correlation. We show that, in such a case, dynamical information is useful to capture a possible correlation.
