For this Virtual Patch I really do not know, because I usually do not pay attention to this knowledge, so I don’t know, but I found a lot of friends who are now in the use of the Virtual Patch, and I find that colleagues are also useful for the Virtual Patch, every time they use when I watch seems very simple, but I don’t know how to get, so I think, since the Virtual Patch so good, I should learn what ah, I don’t know what I should learn is to, otherwise I will never. So I quickly put the Virtual Patch to learn some knowledge, I think this is the case, I will use their own words to some good.
