trivia nuts in Taiwan, and was told that historically +0800 referred to
Chungyuan Time.  Chung Yuan is normally translated as "Central Plains".
After the Pinyan orthography reforms, this is now transliterated as
Zhongyuan, The "Zhong" is the same character in Zhongguo, from where we get
the epithet "Middle Kingdom" for China.

True, but nowadays only people in Taiwan call their time as Chung
Yuan/Zhongyuan/Central plains time despite it is referring to part of
mainland China. The historical name is abandoned and unknown within
mainland China.

I guess it can also be interpreted as C=China, but that would violate the
rule of not to use country name for timezone name, although this is not a
major violation and can probably be explained by stating that the name
china mean something more than the country's name

>> Currently the commentary for Asia/Urumqi says that it covers "Xinjiang
time, used by many in western China". Some people in western China use +06,
some use +08 (Asia/Shanghai in our database), and the geographical boundary
between the two sets of uses is indistinct.

People are aware of both time zones, and choose either +0800 or not if they
are speaking Mandarin, or not.  Hotel receptionists will, when speaking to
foreign guests, explicitly specify timezone, as will local business
contacts.  There is no real geographical line here.

hum yes, the divide is ethnical, but so far all the sources i have read
seems to be for only Xinjiang and none of them cover Tibet/Qinghai, i.e. no
indication saying ethnic non-han in Tibet/Qinghai are also using this
UTC+6. So, where is the boundary that nobody use UTC+6? If it is Xinjiang
only then the commentary can be edited to better reflect the usage situation
