Since we are not getting off the plane will we still be able to use the 24hr free transit?

I'm a us citizen and my gf is a Kyrgyz citizen. We have 3 stops in China. Urumqi. Bejing. And Xiamen. Our total layover time is 24 hours and 10 mins. Our 3rd stop in Xiamen is 1hr lay over and no plane change. Or do we need to get a visa for just transiting through manila? Our trip in starting in Kyrgyzstan and ending in Manila.
