They say these knowledge, how did I not heard of it, it seems that I myself is really too much, no wonder they always say I like it, I is such a person, but I feel I should still learn some knowledge of it, or I will be very embarrassing the. They say is about new property, their understanding of the new property more special, looked at them and said so happy, I can not say a word, because I do not know ah, I feel this is really very awkward, so I think now. I have heard of the new property, I should know about, otherwise next time you hear people say, or let the children into an embarrassing.
