At present, it has not been announced who is the ace technician of Hutu Automobile Maintenance Central China Branch. It is worth mentioning that, unlike the first Ace Technician Challenge, this Ace Technician Challenge is not limited to scribbling technicians, and both the store manager and the front desk can participate.

The 100 technicians who entered the semi-finals were the elites in their respective stores, but the semi-finals they faced were not simple.

The fault diagnosis competition originated from the final event of the last competition. In just 1 hour, two fault points of the vehicle were found and eliminated, and the sense of urgency far exceeded the feeling of conventional vehicle fault handling. As we all know, these faults were set by the "old master", and the hidden, ingenious and layered design hides people's eyes and ears.

The second ace technician rematch not only decided the regional ace technician to advance to the national finals, but also specially set up the honor of "king" in independent regions, namely, the king of tires, the king of word of mouth, the king of brain holes and the king of calls. After six fierce rematch competitions, ace technicians have produced 18 technicians who advanced to the national finals and 46 regional kings' honors.
