Do we need to collect the checkin baggage on direct transit for 24 hours?

Hello
I am travelling from Japan to Delhi via Shanghai on China Eastern. Ihave 12 hours of layover, and i would like to visit Shanghai.
1)Do i need to apply before for the direct transit type? can get it at the Shanghai Immigration?
2)If I get the direct transit type, do i need to collect my checkin luggage or airline will transfer it to next flight?
