With an hourly rate of $500, she works around 50 hours per month. However, the job is really demanding from Mandy's point of view.

After discharged from the hospital, her health condition is not satisfactory so that she has tried to look for another part time job with lesser pressure. Luckily, she receives a job offer from a small trading company with an hourly rate of $300 and she proposes to work 35 hours per month. She hopes this newjob could provide her more rest time for a faster recovery. In addition, her husband suggests her to hire a domestic helper to take care of her as well as to do the housework at home.
