Virtual Patch On this point I really do not know when to sit with my friends talking about this Virtual Patch, I really do not know what to say, I can only sit next to listen to them in this regard the topic, because they are engaged in the same industry for their knowledge Virtual Patch are very understanding, and I will be different, can be a layman, so I think they do not understand there is no shame to say, but I think this knowledge, I should know something, or else they say, I really did not understand it, so I just thought, since they know everything so much, that there is time I must be good to ask them, learn some knowledge.
