will 1 hour time be enough to transfer from another flight in same terminal in Shanghai

I think one hour is not enough. If you have to claim your lugguage by yourselves and the check-in counters will be close 30 minutes earlier usually. Generally, the airlines company will suggest a 2-3 hours for transfer. Easier for a connecting I-I flight, I mean transfer between two international flights. You are not sure if there is deplay or something else happend. So, you need longer time to transfer.
