There was a man who sold horses for three days in a row.
This fable shows that some people do have real talent and learning, but they may not be appreciated and reused, so people like Bole are needed to discover and recommend them. As soon as Bole arrived, the price of horses increased, which shows the importance of authority, but you should not blindly worship and superstitious others, and be more wary of some mediocre people using or borrowing authority to raise their own status. This behavior has also become a "celebrity effect". Dialectically, we should discuss it.
