Hi has anyone on here ever gotten a port visa to enter china mainland?

1] I am traveling a lot through PRC but only get 3days each time. as i am a tongan citizen passport holder.
i was getting the tourist type for a while with single entry/ or 2 entry. but this time around i got told i am now using a port type? never heard of it?

2] Also does anyone know if the 1year type for PRC. is still in use or have they cancelled it completely. 1year type-which gives multiple entry through the year.

3] Can a macau entry permit be apply for at chinese consulate?
