Comments on 'Teleportation of two quNit entanglement: Exploiting local resources'and 'Reply to Yang et al.'s comment'

This paper includes two comments. The first one is a comment on 'Teleportation of two quNit entanglement: Exploiting local resources'. Two different efficient methods are presented to modify some details of N. Ba An's protocol, so that teleportation of two quNit entanglement can be successfully achieved in terms of the revised N. Ba An's protocol. The second one is a comment on 'Reply to Yang et al.'s comment'.
