Real pleasure in finding this forum. I come from China.China is a large country. I have never gone abroad and have not a foreign friend. I'm sorry my English is not good. This is my first time browsing foreign forum, you know it is slightly difficult for me. I like network security very much and I'm still a novice in this field, but I am a keen amateur. My greatest wish is make friends with others here, and learn a lot of knowlogies from here.
