Before
I was in a big construction investment company as a data member,because my
major is Architectural/Engineering Tech.every day facing the computer Filing
Documents,write work letter.the boss was satisfied with my work,my colleagues
have always taken care of me and looked after me,because I was the
smallest company,the only who intern without graduationcertificate.At that time,I have a Independent
free life,I rented a house near the company .cook and wash clothes by myself.
Sometimes go shopping,playing mah-jong with colleagues(in Sichuan
and Guan Dong playing mah-jong is a very common form ofentertainment),
it seems as if I began a easy new life .
