Transit visa for Indian passport holders

I am Indian Passport holder. I am coming from Seoul, South Korea; I have
alien registration card of this country too. While going to India, I have
to come from Seoul to Shanghai PVG airport and then change the airport from
PVG to SHA. Then from SHA I will move to Kunming to Kolkata. Please tell me
whether China eastern airlines will arrange my transit visa and bus ticket
for changing airport.
