Dear, consular. I am Mega. I am an Indonesian, and stay in Japan now for one year until this August. I would like to go to Shanghai on this March. I will enter Shanghai from Taiwan. I only one day in Shanghai for transit flight (from Taiwan to Japan).I would like to have a little one day travelling in Shanghai. Because I will be only day there, do I need visa or kind of permission letter to entering Shanghai?(if so how could I get it?).Thank you in advanced. Have a nice day :)
