説明:

In the previous Letter, Xu et al. reported that edge modes disappear in the expanded structure of the Wu-Hu model characterized by Z2 topological index, while they appear in the trivial shrunken structure, when the edge cuts through the hexagonal unit cell. They then concluded that these edge modes are defect modes lacking topological protection. Unfortunately, their approach is not justified, rendering the conclusion unsolid.
