I need to go to QuanZhou from Xining, which way is the best way to get there? Thank you!!!

Neither direct trains nor flights are available from Xining to Quanzhou. By train, you could make a transfer at Wuchang train station in Wuhan. Or, you could take flight to Shanghai first and then take a bullet train to Quanzhou. If you make a transfer at Wuchang station, the whole train journey will take around 40hrs.
