The experimental discovery of hidden heavy flavor tetraquarks, $Q\\bar{Q}q \\bar{q}$ ($Q=c,b$ and $q=u,d,s$), provides great possibilities for the hydrogen-bond-like structure of the Quantum Chromodynamics version. In this work, considering that the colors of $Q\\bar{Q}$ and $q\\bar{q}$ are both $8$, the tetraquark $Q\\bar{Q}q \\bar{q}$ system is formed by color coupling $8\\otimes8 \\rightarrow 1$.
