pls give me details of bullet train to travel on 14th and 15th of july from guangzhou to shanghai

I'm afraid no bullet trains operate between the two places. As I know, five regular trains run every day and they leave Guangzhou around 18:10, 13:58, 08:00 and 11:10. The travel duration is around 16hours or longer. To save time, you can take a direct plane to travel.
