what do u mean by portals?

A little more info is needed to give an accurate translation. However... Portal is a single-player first-person action/puzzle video game developed by Valve Corporation. A doorway, entrance, or gate, especially one that is large and imposing. An entrance or a means of entrance: the local library, a portal of knowledge. The portal vein. A website considered as an entry point to other websites, often by being or providing access to a search engine. I hope one of these definitions fits your question x
