What is the function of enterprise's unique name?

For example, "Wahaha" and "BBK" are very unique. The former is a children's drink and food, named Wahaha, which makes people clear at a glance; The latter skillfully took advantage of the tendency of China people, especially Cantonese people, to please others. They are all impressive good names. Similarly, there are "Laoganma" and "Tibetan girls" and so on. Small entrepreneurs should pay special attention to this. Since you can't spend so much advertising money to name yourself, it's better to choose a name for the company from the beginning. The company name should be short and lively. Names have fewer words and strokes, which are easy to communicate with consumers and easy for consumers to remember. At the same time, they can also arouse the imagination of the public and have richer meanings.
