Two DVDs.Both I like.One is historic drama.In Qing's dynasty ,seventeen century.They have three emperors,Grandfater,Dad and Son total three generation.I saw dad and grandson before.

One is knowleage DVD,they are all my favorite subjects,The space,eclipse,aurora and deep sea.

I bought 2 books and 2 DVDs.One book is C# language and the other one is VC++.My new company usually use it to develop tools.I couldn't use VC++ so I have to learn ,have to buy one.

I bought C++ when I was university studend.I think C# kind of C++ and also expensive.

So I've spent 400 dollars.
