A shorter and quicker way to guanzhou from the Hkg International Airport

Thanks for above answer, may i know which will be the arrival port from the hongkong international airport, the Fuyong port or the Shenzhen Shekou port, and how long distance between these port to the Luohu railway station? How do i get a transport to the railway station? I m actually finding a shorter and quickest way to guangzhou transiting from hongkong airport, avoiding the time spending for the immigration and long hour coach ride to guangzhou. Please advise, is it more convenient to get a train from hom hum direct to guangzhou?
