Elements of eigenvectors obtained by exact diagonalization can be considered as two dimensional lattice sites, in which dynamics of a given initial state is seen as a percolating procedure on the lattice sites. Then one can use the percolating procedure to generate a series of fragments of eigenvectors. Combining the fraction ratio and entanglement entropy dynamics of the generated fragment we examine the many-body localization transition in a disordered hard-core bosonic model. It helps us to locate roughly the transition point at the critical disorder strength $W_c\approx 12\sim13$. The scaling collapse of the fraction ratios gives us the localization length exponent $ν\approx2.0$.
