Impressed by China's Infrastuctural Development

My name is Alfredo Dos santos Caramelo, and I am from Angola. I am a first year student of civil engineering and am studying in Yangtze University. I heard many wonderful things about China's infrastuctural development and I was nothing but overwhelmed when I witnessed it for myself. I saw a building finish in 6 months here in China which back home in Angola would take about one year and I was very impressed. 
The Chinese language has been a little problem for me,  but now I  know the basics  with the help of my chinese friends, and I can communicate efficiently with fluency.
