Why can't actors use their original names when they debut, and only let the public know their stage names?

People who often pay attention to the entertainment circle will find that many stars are actually using stage names instead of real names, which seems to have become a normal state in the entertainment circle. Then why do many stars debut as stage names? Actually, there is a reason.

First of all, the real names of some stars may be difficult to pronounce, or difficult to remember, which may bring inconvenience to others and reduce the number of people who mispronounce their names when attending activities. In fact, this is not only convenient for yourself, but also for others, such as Andy, whose real name is Yang Ao. Some people who read too fast may turn into urine, which will embarrass themselves and people who mispronounce their names, so many stars don't use it.

Secondly, because many people's names were helped by their parents when they were young, some people may think that their parents' names will be a bit corny and not good for themselves in the entertainment circle, so they will have a better stage name, which will look better when others call them. For example, in rural areas, some people think that cheap names are good for feeding, and I will also give some names to cats and dogs, which may be easy for parents to remember, but to a large extent.

Thirdly, the technology was not developed before, and people's thoughts were not so advanced, so many identical names appeared, such as? Haoyu? Haotian? For example, there are many children with this name like me, so many stars use stage names to avoid the situation of overlapping names, because some people think that overlapping names will appear inferior and lose their identity, so this is why many stars use stage names.

Many people's names may be obtained by fortune telling when they were young, or copied from the dictionary of names, which will lead to many duplicate names, so it is also convenient for people to remember themselves by using stage names by stars.
