any suggestion please...will it be better and possible to travel by train from hongkong to Changchun directly? or should i get hongkong to Beijing first? then Beijing to Changchun, will it be cheaper that way? i'll be in hongkong for a few days then would love to go to Changchun to visit a family friend for a couple of days... They said it would be more convenient to take a flight from HK to changchun but i'm considering the fun of traveling by train plus the costs....Help me please..
