We study the mass spectrum of the $\rm{ q}^3\bar{ \rm{ q}}^3$ mesons both from the quark model with triquark correlations and from common quark model with colormagnetic interactions and with relative S-waves between quarks. Two cluster configurations $(\rm{ q}^3)-(\bar{ \rm{ q}}^3)$ and $(\rm{ q}^2\bar{ \rm{ q}})-(\rm{ q}\bar{ \rm{ q}}^2)$ are considered. In the spectrum we find rather stable states which have the same quantum number with particle resonances which are corresponding to the $p\bar{ p}$ enhancement, $p\bar{ \Lambda}$ enhancement and $\Lambda\bar{ \Lambda}$ enhancement with spin-$\mathbf{ 0}$ or $\mathbf{ 1}$. This imply these enhancements are NOT experimental artifacts. The color-spin-flavor structures of $p\bar{ p}$, $p\bar{ \Lambda}$, and $\Lambda\bar{ \Lambda}$ enhancements are revealed. The existence of spin-$\mathbf{ 1}$ $\Lambda\bar{ \Lambda}, p\bar{ \Lambda}, p\bar{ p}$ enhancements is predicted.
