You are riding in a chariot, and I am wearing a hat. When we meet one day, I will bow to you under the chariot.
When you grow up, you ride in a carriage and are very rich, but I am just a commoner wearing a bamboo hat. When you see me, will you get out of the car and say hello to me?
If in the future, you are a mediocre person and I pass by you on a carriage, then I will also get off the carriage and say hello to you.
