Flying from HK , Macau or Shenzen to Tiajin/Beijing

Hi there...

My companion and I are planning a China trip for mid july and would like some feedback on Hongkong Airlines flying to Taijin (Flight times and illustrative rates roundtrip since they havent answered my email in a month)

Also, any idea of the trip from Taijin to Beijing (bus?)

CX flies to beijing for around USD700.00. too expensive.

We are thinking of train from Hunghom (I think its 1 whole day of travel) then from Beijing, go to Xian and others. Unfortunately, Shanghai is in the other direction and might not be a good and economical idea to squeeze in sadly ( I love Shanghai)

Thanks and any feedback would help.

I think there%26#39;re buses directly from Tianjin airport to Beijing, journey should take about about 1 hour or so.
