No thought of this role of NVR is really big, because I really never concerned about this NVR, because I had really rarely use this NVR, especially this time I really see is still inside the company to a group this NVR, especially our company also is really doing better and better, there is no thought that I still can learn a lot of things, especially I don’t know the role of NVR before, this time I really feel that NVR is a very good use, and use also really is particularly large, our company now has really been with this NVR.
