train from guangzho to qingdong & how many time

by Qingdong do you mean Qingdao in Shandong Province?
if yes, there are G276 and T161 running from Guangzhou to Qingdao. It takes 13 hours on G276 and 29 hours on T161. But G276 runs in daytime and only has first class, second class, and business class seats. T161 runs overnight and has soft sleepers.
