I am going to renew my passport in the Indonesian Consulate located in Shanghai.

Generally, the pasaport will be held in the consulate. What is an alternative document that I have to prepare if I need to get back to Shaoxing by intercity bus or speed train when my new passport is being processed? The officers in the train station or bus station won't let me purchase the ticket withouth passport. Can I request a letter from the local police or authority that can allow me to take the intercity transportation?
