有關英文句子既問題

I have been a hawker.
原則上是無問題的,但最好說明時間,但我覺得用 I am a hawker,用意是說明自已是小販,又可必加have been 呢。

如果話有冇錯,就錯在have been果到!
應該具體說明
hope can help you^_^

這句意思是"你曾經是一個小販"
是否你想要的意思/意思有無錯只有你才知道
英文文法結構和組句上無問題
001的回答亦對-一般英語句法寫出"曾經"都會加上時間的指示(由何時開始或直至甚麼年份等)
I've been a hawker since 1997.
I've been a hawker until 2013.

May be Kit wants to emphasize his experience in the business of a hawker.
Rewrite: I have been working as a hawker for many years.
I have been in the hawker business for quite some time.
