Given a travel related situation, and given a specific question about the situation, summarize the question into a title
One example is below.
Q: The green carriage is of course first class. This would be our first preference with our 5 month old baby in lap, because of the presumably larger toilets for changing and whatnot. However, the baby being a Western white baby... will occasionally babble, screech or cry uncontrollably for a little while.

Speaking in terms of Japanese culture, should we avoid Green class tickets if we are taking aboard a potentially disruptive baby?

A: Japanese train etiquette: Is it acceptable to take a baby in the Shinkansen Green Car?
Rationale: A person gives a detailed description about a situation where they would prefer to travel on the Shinkansen Green Car but is doubtful if doing that would be against the Japanese train etiquette since they will be traveling with a baby. The question is summarized as Japanese train etiquette: Is it acceptable to take a baby in the Shinkansen Green Car? for easy indexing the next time someone searches for a similar phrase
Q: I have a 75 hour trip to Beijing (PEK) coming up in October. I shall enter at PEK on a flight from London, arriving at 0930 and continue onwards by air to Hong Kong three days later at 1230, and I shall be travelling on an ordinary British passport.

I understand that the 72 hour transit visa on arrival actually begins the midnight after my arrival (and not immediately after arrival). The relevant text from TIMATIC is
Visa required, except for Holders of British passports
endorsed British Citizen holding confirmed onward airline
tickets to a third country, if arriving in and departing from
the same city:
- at Beijing (PEK), Chengdu (CTU), Chongqing (CKG), Dalian
(DLC), Guangzhou (CAN), Hangzhou (HGH), Shanghai Hongqiao
(SHA), Shanghai Pudong (PVG), Tianjin (TSN), Wuhan (WUH),
Xi'an (XIY) or Xiamen (XMN) for a max. transit time of 72
hours, starting from 00:01 on the day following the day of
entry.
- at Guilin (KWL), Harbin (HRB), Kunming (KMG) or Shenyang
(SHE) for a max. transit time of 72 hours;

However, although several non-official sources substantiate this distinction, I cannot find any official confirmation of this. Does anyone have any experience in doing this kind of transit?
