I want to travel from Riyadh to shandong

From where you are, you need fly to Dubai first and then fly to Beijing.
From Beijing, you can find the bullet trains for Jinan, the capital city of Shandong Province.
The flight ticket price is hard to tell, because different airline companies in different time have different prices, so for the detail prices, it is suggested to contact the airline company. I know the flights from Beijing to Dubai are operated by Emirates and Air China.
For the accommodation in Jinan, the comfortable 3-star hotels charge around 200 to 300RMB per person for a standard room. If you want to leave in express hotels, it is around 200RMB.
