“我去了合肥”怎么翻译

去了有没有回来呢？
如果说去过就用I have been to HF.
如果现在就还在I have been in HF.

I have gone to Hefei/I have been in Hefei/I am already in Hefei.都能表达这个意思。
但是不能用I have been to Hefei. 那是"我（曾经）去过合肥"的意思。

I went to Hefei.
或
I've been to Hefei.

"I have gone to Hefei"

I have gone go He Fei.

I have gone to hefei.
