@ziawj2,
Lose the quotes around
English Speaking Contest. They are unnecessary and, in fact, imply that it's not a real contest (quotes, when they aren't titles or quotations, imply sarcasm).
Change
our university to
Hubei University. Use the actual name.
Work experience, not
experences, which is not a word. Keep this as a singular (it's the experience of only one person, you).
I would also put more information into your work experience. Just saying you were a sales person at the market doesn't tell me much. Did you exceed your quota every month? Write up new policies? Receive written letters of praise from customers? Get a recommendation as Employee of the Month? Even if you didn't get these kinds of accolades, you can write things like (assuming they're true, of course),
Sold 100 units per hour in sales contest or
Sold 100 units per day consistently during first month of employment, escalating to 1000 units per day consistently during last month of employment.
The assistant account work could also use description. Did you check tax forms, organize books, check someone else's work, overhaul the computer programs? There has to be something in there for an employer to get to understand what you were doing. Not every accountant does the exact same thing - you know this. You've seen fellow employees doing different things. So how is an employer supposed to know which specific thing you were doing unless you mention it?
This is usually done in the form of bullet points, which are hard to show on a forum like this, but look like
- a bullet point
- another bullet point
Also ditch the question mark in front of the word
Hierarchical.
And ... good luck!
