Time zones are named /after/ the most populous municipality in the 
area to which it applies, often but not always the capital: users 
in areas where different time zones may apply, may choose whichever 
of the alternatives applies to their uses of the time. 

See	https://github.com/eggert/tz/blob/master/Theory

Selecting time zone Asia/Shanghai gives Beijing time, and Asia/Urumqi 
Xinjiang time. Users in Xinjiang may choose whichever time zone suits 
them: government offices in the area mainly use Beijing time, others 
use Xinjiang time.

Try the example time zone selection UI 'tzselect' provided with the 
package, select 4) Asia, 9) China, and you are offered the choices 
1) Beijing Time, 2) Xinjiang Time. Both zones are associated with CN 
in tzdata zone.tab and zone1970.tab. 

If the UI or device you are using does not offer the choice, contact 
their support for workarounds or alternatives. 

For example, Windows 10 seems to support only:
(UTC+08:00) Beijing, Chongqing, Hong Kong, Urumqi
