A graph is called distance integral if all eigenvalues of its distance matrix are integers. In 2014, Yang and Wang gave a sufficient and necessary condition for complete $r$-partite graphs $K_{p_{1},p_{2},\\ldots,p_{r}}=K_{a_{1}\\cdot p_{1},a_{2}\\cdot p_{2},\\ldots,a_{s}\\cdot p_{s}}$ to be distance integral and obtained such distance integral graphs with $s=1,2,3,4$.
