So do scholars. Yue didn't have a car, but a tourist from Yue got on the bus in the suburb of Jinchudi. The spokes of the car were rotten and the wheels collapsed. When the pin at the joint between the axle and the truck scale is broken, the axle is useless. But because his hometown never had a car, he took a boat home and boasted in front of everyone. The spectators listened to his boasting and thought that the car was like this, and people followed suit. One day, people in Chu Jin laughed at their clumsiness when they saw their cars. The Vietnamese thought it was self-deception and ignored it. When the enemy invaded their territory, the Vietnamese drove a broken car to resist the enemy. The car broke down and was defeated. I still don't understand the reason for the car.
This is what learners should worry about.
