Hello, I booked a flight From Seoul to Hangzhou with 1 stopover.

The flight will go from Seoul to Qingdao Liuting International Airport to Hangzhou. After booking the website shows this note which says ( Please note: According to the laws of the destination country, passengers from certain countries traveling on a one-way ticket must hold a student visa, immigrant visa, work visa or other long-term visa. Please confirm your visa status before buying a one-way ticket.)

what does this mean? Am an indian and i hold a valid chinese visa but here they are saying certain nationalities required immigration or student visa? Does this mean that i can't transit inside china from one airport to the other with Tourist visa. Plz clarify
