It's best to disable View->Object Shading->Edges on Unselected during retopo jobs.

unfortunately dont work(

Can you post a screenshot?

ye,in f1,f2,f3 same

Strange. If you're using my configuration, everything should be set up properly by default.
Did you freeze your reference mesh? If you're still getting wireframe on reference mesh, you may try disabling "View->Object Shading->Show Edges on Frozen", but it should already be off.

Take a look at this short video clip about preparing reference mesh for retopologization:
