Why did Wu change his name to Aaron?

One is because his real name is Wu He, and two surnames in a group will conflict, which will make it difficult for fans to remember or confuse, and Wu is also difficult to remember. Plus their names are fortune-tellers, and they all use better names. Just like taking the middle of the name and changing it to Cheng, Confucianism changed its original name to Chen Weijin. And it's not a name change, it's just a stage name. Many stars know each other like this. Jerry Yan's real name is Liao Yangzhen, and now it has changed beyond recognition.
