This fascinated me.
I put together this little background from reading around 20+ responses on what seems to be a Quora-type section of Baidu.
I have DeepL and a web browser, and I'm not afraid to use them
"There must be a road before the car reaches the mountain, and there must be a Toyota car if there is a road"
The text is from a Toyota advert, from many years ago, in China (hence being in Chinese).
The ad was very successful and widely remembered in China. The "tag-line" stuck, even though Japanese cars were not popular in China, because Toyota impressed the demanding Chinese people with it's reliability and strength.
The phrase quotes meaning and words from a proverb:
"When a car reaches the front of the mountain, there must be a road, and when the boat reaches the bridge, it will naturally go straight",
and an ancient poem:
"There are no roads when mountains and rivers are full of doubts, and there is another village with dark willows and flowers".
Anaysis of the advertisment shows the pillars of it's message.
1. The advertisement does not directly promote the quality of the product, but uses the implication of sales volume to show it;
"Where there is a road, there must be a Toyota car" ie they are EVERYWHERE;
2. It shows the quality of the car. Strong and adaptable.
"Where there is a road, there must be a Toyota car", implies that no matter what road, Toyota cars are up to the task;
3. It shows strong self-confidence, the double use of
"must" , the tone is firm, giving people a feeling of trust.
