Given a travel related situation, and given a specific question about the situation, summarize the question into a title

Ex Input:
In the Chinese visa form it says


  Applicants who were born in Turkey or who have travelled to Turkey must provide an original personal letter. This letter should state the detailed reasons for travel to Turkey and specify the exact date(s) of entry, exit, and duration of the stay(s). Additionally, a photocopy of the Turkey visa (if applicable) and all entry and exit stamps must be provided.


I'm curious why a Chinese visa needs a personal explanation about visits to Turkey.
Would visits to Turkey before China be a negative point when applying for a Chinese visa?



Ex Output:
Why does the Chinese visa form specifically ask about visits to Turkey?

I am a frequent traveller with Etihad program, so I have miles there. Alitalia is in the Etihad Airways Partners program, so whenever I fly with Alitalia I still save my miles on the Etihad program. 

Next month I have a flight with Aeroflot: looking at their loyalty program, they are in SkyTeam, which involves also Alitalia within the partnership. 

How is it possible that flying with Alitalia I can be in two different loyalty programs? 

Will I be able to use the miles with Etihad program?

Should I join the SkyTeam Alliance (but I didn't understand which of the "sub-alliances" I should apply for)?

How can I earn miles from these flights and enjoy them? 

I am also in the Miles&More frequent traveller program, but I think for this flight it is useless. 


Ex Output:

I am required to pick someone up at the CDG airport. I live in Gif-sur-Yvette in ile-de-France and can get to RER stop "CDG 1" (that caters to CDG terminal 1). I read that I would need to take the CDGval to terminal 1. 

However, the map of terminal 1 level and CDGval level  doesn't quite tell me how to get from the CDGval stop for T1 to the arrivals of T1. There appear to be several "levels" to T1.

Also Is there a particular gate at T1 that arriving passengers exit through? My passenger will be arriving on United airlines.
