I want to go Qingdao for business, pls tell the easiest way from India

May I know which is your departing place in India? Anyway, you can consider flying from India to Shanghai and then transfer another direct plane or high-speed train to QD city.

you can check eastern china airline which have a stop in Kunming and then arrive to Qingdao . secondly you can check the fair for cathay pacific airline which fly to between India and Qingdao Via HongKong. the least and most cheapest is air asia which arrive till Shanghai and you can book domestic to Qingdao onward.
