If not a friend, I think I will not buy such a good NVR, so I think it, I still should thank a friend’s. Just yesterday, our leaders said let me go to buy a NVR, because I of this NVR is not very understanding, so I was thinking of how to get a good NVR, then I would think of a friend, because he usually love to study NVR knowledge, so I let friends accompany me to buy the NVR NVR, later we bought a particularly good, especially the leaders also praised me, so I think that no matter what, I would like to thank the help of friends are, if not his words, I will not buy such a good NVR.
