How many days does it take to check the car from Chengdu to Changchun?

It is about1.650km from Chengdu to expressway in Beijing (via Xi 'an, Taiyuan, Shijiazhuang and Beijing), and about1.000km from Beijing to expressway in Changchun (via Jingshen and then to Changchun). The total distance from Chengdu to Changchun is about 2700 kilometers.

Large trucks travel about 700- 1200 km on expressway every day, depending on the driver's driving situation. Then the travel time should be 3-5 days, considering that there are many mountain roads in Chengdu.

You are checking a car and need a special truck. It may take 2-3 days to find a car.

To sum up the calculation time, I think it will take 5 days at the earliest and 9 days if it is slow.

I hope the above answers are helpful to you. Good luck!
