There are many results about the structures of the tame kernels of the number fields. In this paper, we study the structure of those fields $F$, which are the composition of some cyclic number fields, whose degrees over $\mathbb{Q}$ are the same prime number $q$. Then, for any odd prime $p\neq q$, we prove that the $p\mbox{-}$primary part of $K_2\mathcal{O}_F$ is the direct sum of the $p\mbox{-}$primary part of the tame kernels of all the cyclic intermediate fields of $F/\mathbb{Q}$. Moreover, by the approach we developed, we can extend the results to any abelian totally real base field $K$ with trivial $p\mbox{-}$primary tame kernel.
