  "abstract": "Let ${\\mathcal{P}_{n}}$ denote the set of positive integers which are prime to $n$. Let $B_{n}$ be the $n$-th Bernoulli number. For any prime $p \\ge 11$ and integer $r\\ge 2$, we prove that $$ \\sum\\limits_{\\begin{smallmatrix} {{l}_{1}}+{{l}_{2}}+\\cdots +{{l}_{6}}={{p}^{r}} {{l}_{1}},\\cdots ,{{l}_{6}}\\in {\\mathcal{P}_{p}} \\end{smallmatrix}}{\\frac{1}{{{l}_{1}}{{l}_{2}}{{l}_{3}}{{l}_{4}}{{l}_{5}}{l}_{6}}}\\equiv - \\frac{{5!}}{18}p^{r-1}B_{p-3}^{2} \\pmod{{{p}^{r}}}. $$ This extends a family of curious congruences.",
