Hello, I am a Mexican living in France. I will be traveling to Rome in september for only two days (sept 14-15). I have the following questions:

1. Is it possible to obtain a Chinese visa in a single day?

2. Do I need to make an appointment first or can I show up at the embassy just with the required documentation?

3. I have electronic tickets (Expedia) for my flights to China, is it OK to present only the printed version of the tickets (same for hotel reservations)?

Thank you very much in advance!
Best regards!
