Abstract
In this paper, we prove that if two distinct non-constant meromorphic functions $f$ and $g$ share four distinct values $a_1, a_2, a_3, a_4$ \DM \ such that each $a_i$-point is either a $(p,q)$-fold or $(q,p)$-fold point of $f$ and $g$, then $(p,q)$ is either $(1,2)$ or $(1,3)$ and $f, g$ are in some particular forms.
