chnbjs, chntjs, chnjjjs: Beijing, Tianjin, Jing-Jin-Ji Inter Expwys [Ready]

[Nagamasa]

Three new systems:

• chnbjs: Beijing Provincial Expressways
• chntjs: Tianjin Provincial Expressways
• chnjjjs: Jing-Jin-Ji Interprovincial Expressways (short for Beijing, Tianjin, Hebei)

Note: S3305 remains unsigned but fully concurrent with S6. chng in CHN-BJ and CHN-TJ can also be reviewed.

The subject* indicates "Ready". Does it refer to "preview" oder "ready for review"?
Just by reading your post, I think that we should only review chnjjs once the Hebei Provincial Expressways are in preview too.

*We do usually not indicate the system status in the subject. We use this post for indicating status changes.
