I often get calls asking me to go to XX Hotel to hold some trade fairs and meet small business owners. Waiting for this kind of call.

There is a 90% chance that the company will take this opportunity to promote its products, and the most important thing is to see if it is useful to you. If the other person is vague or has nothing to do with your industry, you don't have to attend, wasting your time.

You need to know what kind of information you need to know and where to get it. This is the most important thing.
