i want to go to jining from shenzhen or guangzhou. How can i go there cheaply and easily and how time needs?

Hi, considering all, if you leave from Shenzhen, it is suggested to take a plane to Jinan in two hours and three quarters. I remember there are direct buses from the airport to JN then

From Guangzhou to JN, only one direct train is in operation - T180, which can take you to the destination in around 19h and it shall be the most cheapest way.
