Echelon-Ferrers is one of important techniques to help researchers to improve lower bounds for constant-dimension codes. Fagang Li [6] combined the linkage construction and echelon-Ferrers to obtain some new lower bounds of constant-dimension codes. However, this method seems incorrect since we found a counterexample.
