After having completed the study of public relationship and advertising course in Jinan University, I had worked in --ABC--Company for about five years, and then I changed to work in --DEF--Company for one year in order to get a higher pay. As the work is on the day and night shifting and I 'm not get used to it. Owing to this disadvange, I wish if I could change to the office work. Because I had years' experience in dealing with book keeping and finance and for the time being to keep on studying accounting and English conversation courses. Therefore, I'm sure I can do the office work as required.
