The pairwise NQD sequence is a general class of random variables which has been widely utilized both theoretically and practically. The purpose of this paper is to discuss the strong convergence of the general pairwise NQD random variables. By applying the pairwise NQD three theorem, the property of pairwise NQD sequences and truncation methods, a class of strong limit theorems for the pairwise NQD random sequences are established. Furthermore, we give a series of examples which indicate that the results of this paper extend the previous ones.
