How and where can I get visa to enter Zhuhai?

I dont know about other Countries but I am a USA citizen I went to China to visit My Japanese friend who moved there. She said I didnt need one because she didnt. However i took het word for it. However. When I got there I found out as an American I DID have to have one.

So after much hassle trying to find someone to speak English they let my friend in to explane to me Why I was being detained.

Long story short. It cost me $800.00i psid 800$ to fly to hongkong slept on a bench in the airport untill the office opened. More money dpent and 5 hours lster. I finally got a one to go back to mainland.
