How many train ticket offices are there in Hanzhong? Where is it?

You mean Hantai District. There is one behind Guhantai and Wanbao Mall, and then there is one at Tianhan Avenue Stadium and one at the railway station. Pastoral, postal, Hanyuan, Shishi and other hotels have places to book tickets. Yes, there is one in Dahekan Square. There seems to be a lot of people now, but I suggest you go to Guangzhou again in a few days. There are many people going to Guangzhou now. . . .
