Do not rely or call on anything else as it's TIMATIC on which China Southern will rely. Once you are certain that you have it correct, ask China Southern to note your mother's record so that the problem doesn't reoccur.
3. In reading the TIMATIC entrey for a citizen of Taiwan, resident in the USA, traveling to Taiwan with a <24 hour connection in the PRC and on a Taiwan passport, the problem doesn't appear to be with a visa, but with the fact that the PRC doesn't recognize the passport so the TWOV rules don't apply.
TIMATIC is also available through a link on the SkyTeam website. It prints out with the SkyTeam logo when you make a hard copy to bring, so CZ might give this more credibility than the *A version.
IME DL doesn't seem to pay attention to notes in the record about visa regulations and DL agents aren't eager to add such notes to the record. The attitude is that the agent who issues the "DOCS OK" check is ultimately responsible.
If PRC doesn't recognize Taiwan passports, is it then true that no one who is only a citizen of Taiwan can enter China? Is the problem more specifically that citizens of Taiwan are, according to China, necessarily citizens of China and thus should enter based on travel documents from mainland China, perhaps with some exceptions if someone is a citizen of Taiwan but not ethnically Chinese/of Chinese descent? So are the flights between mainland China and Taiwan then filled with people from then mainland who are visiting Taiwan and not the reverse?
