What were the vehicles like in Zigong twenty years ago?

Tractors are snapping up, trucks are still carrying goods on expressway, trucks on Sichuan Road are busy carrying goods, and there is an airbag on the top of the bus in the city. If the airbag is inflamed, the whole car should get off outside the gas station and wait until the airbag is full before getting on the bus and moving on. Two-wheeled drivers began to turn around in the street with helmets: let the people they met for the first time think they met the bad guys, and then they knew it was two-wheeled soliciting; There aren't many cars on the road. . .
