Getting on the expressway is not free, but there is a charge. During the four legal holidays of Spring Festival, Tomb-Sweeping Day, May Day and National Day, only seven passenger cars (including seven) can take the expressway free of charge, and all trucks and eight or more passenger cars still have to collect tolls.

Main advantages:

Don't reverse the car after crossing the intersection: it is common that the exit doesn't go out. I believe many drivers have had this experience. The common practice of most people is to drive indirectly and get off at the next intersection.

If you reverse at high speed, your life is likely to be in danger. It is precisely because of this kind of thinking that the traffic control department has formulated the most severe penalty for high-speed reversing, indirectly deducting 12 points.
