Add a navigation link on Product details page

[zengfuxu]

I have a link on a webpage "Popular Products" which, when clicked, will open the Product Details page to view prices and description. I wish
to have a button or link on this VM Product Details page so that user can click that button to get back to the "Popular Products" page. (The default
"Back to Category" button will open a page with all Products which I don't want, and I am going to hide that button). How can I add such a button
or link in the VM Product Details page to go back to my "Popular Products" webpage? Please help. Thank you!
