There are times when after the scene is done the actress speaks about the lift, whether is was easy or hard, etc. Once in a while, an actress has commented that she did not do the lift.
There have also been many "making of" videos showing how the actress prepared to lift the guy.
There is also the issue of having body doubles do the lift rather than the actual actress. Any stunt double would almost certainly be strong enough to lift and carry a normal sized man.

As for Jona Xiao I commented a few days ago,
she played in several movies,
and together she showed a great ability in giving piggybacks.
So she has a double capacity, play a role and carry a partner.
I thing thar most girls in this thread are similar, with more or less ability.
However on a very short sequence, or if the scene is in the darkness, they could probably be replaced by a stronger women
