Why my extension is always rejected?

[孟庆龙]

I had make a chrome-extension last week and uploaded it,and i was rejected. 

I read the Developer Terms of Service and Developer Program Policies thoroughly.

I found nothing wrong with my extension. I removed some words in the description which may sound exaggerated, but my extension was still rejected from the store.

I really don't know what went wrong.

Could you please explain why it was taken down every time?
