麻烦英语好的朋友帮我改一下错。

I worked as a data member in a big construction investment company, because my major is Architectural/Engineering Tech. As my job required，I should face the computer to fill documents and to write work letter every day. The boss was satisfied with my work. Because I was the smallest and the only who joined without graduation certificate in the company, my colleagues have always taken care of me. At that time, I rented a house near the company. I can cook and wash by myself and I felt free and independent.
Sometimes, I went shopping, playing mah-jongg with colleagues (in Sichuan and Guan Dong playing mah-jongg is a very common form of entertainment), it seems as if I had began a easy and new life .
