Symmetry distribution between hook length and part length for partitions

It is known that the two statistics on integer partitions ``hook length" and ``part length" are equidistributed over the set of all partitions of $n$. We extend this result by proving that the bivariate joint generating function by those two statistics is symmetric. Our method is based on a generating function by a triple statistic much easier to calculate.
