A little puzzled! What is your itinerary currently? If you are in Shanghai currently, you could go to Hangzhou by train for one-day trip conveniently. However, you could also take the early flight to Xi'an and then head to the Terra-cotta Warriors and Horses directly. A late night, you could fly back to Shanghai. Obviously, it will take more money to Xi'an.

If you were in Beijing, please consider taking a night train to visit Xian. The train could arrive in Xian early next morning, and then after one-day's travel to the warriors and horses, you could take a night train back to Beijing.

Thanks for replying so quickly. I arriving in Shanghai for three days 6-24 to 6-27. I was thinking of taking the train to Hangzhou for two days but after investigating Xian thought I should either to skip it completly or just go for one day. From Hangzhou I was planing on flying to Beijing for three nights and then fly to HK for my last two nights. I am in China from the 24th leaving the 5th out of Shanghai. Again thanks for the help.
