  "abstract": "<p>By analyzing $\\left(27.12\u00b10.14\\right)\u00d7{10}^{8}\\text{}\\text{}\\psi \\left(3686\\right)$ events collected with the BESIII detector operating at the BEPCII collider, the decay processes ${\\chi }_{cJ}\\to 3\\left({K}^{+}{K}^{-}\\right)$ ($J=0$, 1, 2) are observed for the first time with statistical significances of $8.2\\sigma $, $8.1\\sigma $, and $12.4\\sigma $, respectively. The product branching fractions of $\\psi \\left(3686\\right)\\to \\gamma {\\chi }_{cJ}$, ${\\chi }_{cJ}\\to 3\\left({K}^{+}{K}^{-}\\right)$ are presented and the branching fractions of ${\\chi }_{cJ}\\to 3\\left({K}^{+}{K}^{-}\\right)$ decays are determined to be ${B}_{{\\chi }_{c0}\\to 3\\left({K}^{+}{K}^{-}\\right)}=\\left(10.7\u00b11.8\u00b11.1\\right)\u00d7{10}^{-6}$, ${B}_{{\\chi }_{c1}\\to 3\\left({K}^{+}{K}^{-}\\right)}=\\left(4.2\u00b10.9\u00b10.5\\right)\u00d7{10}^{-6}$, and ${B}_{{\\chi }_{c2}\\to 3\\left({K}^{+}{K}^{-}\\right)}=\\left(7.2\u00b11.1\u00b10.8\\right)\u00d7{10}^{-6}$, where the first uncertainties are statistical and the second are systematic.</p>",
