Some comments on the note "Comment on 'Single-parameter quantum charge   and spin pumping in armchair graphene nanoribbons' by Zhu and Berakdar   (arXiv:1207.3457)"
  In response to the comment by Zhu and Berakdar (arXiv:1207.3457) that the physical system considered by them in their previous work [Ding et al., PRB 84, 115433 (2011)] is conceptually different from ours in the appendix of our latest paper [Zhou and Wu, arXiv:1206.3435], we show why they are relevant and further point out conceptually the problems in their work. We also point out that the main supporting arguments in their comment are incorrect.
