What do you mean, traveling without pursuit is not appropriate?

It means that when you go out to do business, you don't meet noble people (that is, your career is very difficult without the help of noble people), and what you plan to do is not suitable (that is, although you have courage and intelligence, you are not born to do business).

When you don't meet someone, it doesn't mean that you can't find someone, because you want to find someone at that person's residence, instead of wandering around the street trying to meet them, so you can't use "travel" and often visit friends. It doesn't mean that you can't do something because it can't be interpreted as success. It has never been mentioned in ancient and modern dictionaries. This should be interpreted as should, appropriate and appropriate.
