i want to travel from meizhou to shangqui and from shangqui to GuangZhou East

There is no direct one available, You need to go Guangzhou first and then to Shangqiu. The there is only slow ride available between Guangzhou and Shangqiu. If you want a faster one for this GZ to Shanghqiu trip, you can connect at Zhengzhou once. So it would be like Meizhou-Guangzhou-zhengzhou-Shangqiu, if you can bear this route. It is the same to back to guangzhou trip. Shangqiu-Zhengzhou-guangzhou.
