Didn't disappear. Xu didn't disappear, she just gradually reduced her activities in public. Xu is a famous actor, director and screenwriter. She has achieved great success in the entertainment circle. However, with the passage of time, Xu gradually shifted her attention to her personal life and other careers, so she made relatively few public appearances. Besides, Xu has always kept a low profile and doesn't like to expose his life and work too much. Therefore, her "disappearance" may only be because she chose a more private lifestyle, not because she quit the entertainment industry. In short, Xu has not disappeared. She is still engaged in her own acting career, but she is relatively low-key.
