Nonstrange hexaquark state q3q3 spectrum is systematically studied by using the Gaussian expansion method in flux tube models with a six-body confinement potential. All the model parameters are fixed by baryon properties, so the calculation of hexaquark state q3q3 is parameter-free. It is found that some ground states of q3q3 are stable against disintegrating into a baryon and an anti-baryon. The main components of X(1835) and X(2370), which are observed in the radiative decay of J/\ensuremathψ by BES collaboration, can be described as compact hexaquark states N8N8 and \ensuremathΔ8\ensuremathΔ8 with quantum numbers IGJPC=0+0^\ensuremath-+, respectively. These bound states should be color confinement resonances with three-dimensional configurations similar to a rugby ball, however, X(2120) can not be accommodated in this model approach.
