What does Fei Biao mean by showing readiness for backup? Did you land at another airport?

The original destination airport may not be allowed to land because of meteorological conditions. If it is determined that it will improve for a while, it will fly to the alternate airport to land, and then fly to the destination airport after the weather at the destination airport improves.

The meaning of alternation:

When the plane cannot or should not fly to the scheduled landing airport or land at the airport, but land at other airports, it is called alternate landing.
