There must be a road for cars to reach the mountain, and for boats to reach the bridge.

The interpretation is that when things come to an end, there will naturally be a solution. Often used to comfort people in trouble.

The advertisement launched by Japan's Toyota Motor in China adapted this saying and modified it to: There must be a road before the car reaches the mountain, and if there is a road, there must be a Toyota car. Later, he was jokingly said: "There must be a road before the car reaches the mountain. If there is a road, Toyota cannot stop."
