We are packing our stuff into boxes to prepare to move to new house. I can’t imagine we still have some many textbooks that used during our college time. We were browsing through those textbooks like networking, C++ programming, software engineering and etc. When we think back, we really passed back all these knowledge to our lecturer. Frankly speaking, except for networking like TCP/IP is useful to me, the rest are really useless now. Therefore we decided to donate these textbooks to those people who need it.
