Mnl - XIAMEN GAOQI - LAX

My wife and I want to travel from Manila to Los Angeles. Enroute there is a 22 hour stop over in XIAMEN GAOQI and on the way back a 6 hour in XIAMEN GAOQI and another for an hour and a half in QINGDAO. She is Filipina I am US/Canadian (dual). Will we be allowed the 24 hour transit status? No one from the airlines seems to have a clue!!
