I'll fly Dhaka-Kunming-Shanghai-Incheon.I'll arrive Changshui Airport at 7 pm.I've 12 hour layover there.

Hi, you can stay at the hourly lounge in the airport, where you can have a rest nd have a shower. I heard it costs CNY50 per hour and you get discount for longer stay.

Hello!
thanks very much for your kind reply.I'm afraid, it seems to me expensive.is there any other option..something cheap?any bangladeshi rest house to stay at night?

Regards,

One of my friends just came back from China. He said that he was told there was Bangladesh rest house around KM airport, but he failed to find that. You may have a try upon your arrival!

Finally, i got a great experience of long stay (12 hr) at KM airpport. well, i found Bangladeshi people just outside of the airport. They provide accommodation+pick up to & from airport+food.I really liked it.the guest house is close to the airport.it cost only $17 for everything.The place where I stay was:
China Bangla Guest House
I really enjoyed the trip.
