django output wrong media url - django

Question

Django version is 1.10.3
Static file server is nginx
Debug mode off
The output media url has an absolute path in the server.
eg: http://127.0.0.1:8001/home/ken/hc/media/uploads/q/2017/03/01/hjqtye.png
The correct url is: http://127.0.0.1:8001/media/uploads/q/2017/03/01/hjqtye.png
How can i fix it? THX.
