Can I buy a train ticket without an ID card? In what way? For example, can I take photos with my mobile phone?

You can buy a train ticket without an ID card, but you need other documents.

1. If you don't have an ID card, you can also buy a train ticket with your household registration book, motor vehicle driver's license, temporary id card (within the validity period) and other documents that can prove your identity.

2. If not, you can go to temporary id card to reissue the counter and tell the relevant staff about yourself. You will be asked to provide your ID number, and a temporary id card will be sent to you after confirmation (valid for only one day).
