Dude, your question is too profound. From Yanshan to Leling (40 km), it takes about 1.5 hours to drive a troika, and it takes about 25 minutes to drive a Mercedes. (except too fast or too slow)

The salary of Yanshan State Taxation Bureau is about a month for cleaning in 500 yuan, and the director doesn't cap it (the Commission for Discipline Inspection doesn't know).
