transfer @ Xiamen

i have a 2 entry visa and on my arrival at Xiamen airport AT 10.15AM I will be catching a connection flight to Hong Kong at 12 10, I am using 2 different airlines and I have to transfer my own luggage! will i lose one of my entries by doing this even if i dont leave the airport? will I have to clear passport control in order to collect my luggage? and will I have to clear customs in order to check in for my connection flight?
