Is it clear?

Bureaucracy is confusing the word over.
In the US they're fond of abbreviations. The office in China would be listed as:
TCADPRMB-Deputy Director-Liu Bo

Where I live the local paper would probably say "A senior official in the city's roads department".

It is a little complicated to understand.
I'd look at shortening the title



Tianjin city: Is there a different area that has the same Tianjin name that could be confused (such as Tianjin prefecture or state). does that area have a toll rate office? If not then "city" is redundant

Is there another office for private roads? If not then "public" is redundant. Most roads (unless privately owned) are public anyhow It doesnt need to be stated.
"road management bureau" is redundant as tolls only occor on roads. Is there a separate office for tolls on bridges?
this leaves us with....
TCAD Toll Office Deputy Director....

Thank you all.
