  In this paper, we make use of holographic Boundary Conformal Field Theory
(BCFT) to simulate the black hole information problem in the semi-classical
picture. We investigate the correlation between a portion of Hawking radiation
and entanglement islands by the area of an entanglement wedge cross-section.
Building on the understanding of the relationship between entanglement wedge
cross-sections and perfect tensor entanglement as discussed in reference [1],
we make an intriguing observation: in the semi-classical picture, the
positioning of an entanglement island automatically yields a pattern of perfect
tensor entanglement. Furthermore, the contribution of this perfect tensor
entanglement, combined with the bipartite entanglement contribution, precisely
determines the area of the entanglement wedge cross-section.
