I plan to go to Taiwan to attend the conference for a week with the original copies of the Hong Kong and Macau Exit Permit, passport and Taiwan entry permit. A friend just went and it works. He also said that he could buy a joint ticket directly, and he used an electronic ticket. Questions: 1. Can I buy a connecting ticket directly? 2. Can I buy an e-ticket on Ctrip? 3. Are all air tickets booked with passports? Can't you use your resident ID card? 4. Can you directly exchange two boarding passes for one-way boarding in Shanghai? 5. Do I have to buy a round-trip ticket before going? Please answer with similar experience, how is it safer to use this method to go to Taiwan. Thanks in advance!

Will there be any problems when exiting customs in Shanghai? (Supplemented at 2009-10-23 18:31:54) Thank you both for your answers. I would like to ask again, will there be any problems if the Hong Kong and Macau Exit Permit does not have the entry and exit records of Hong Kong Customs after returning? Will he come back and be questioned, leave a bad record, or affect the next application for endorsement? Is it necessary to exit and enter the customs once at the Hong Kong Airport with the Hong Kong and Macau Pass?
