Liu Pinyan's temperament does have a certain relationship with her age, but it is not absolute. Temperament is a comprehensive embodiment, including personal character, cultivation, life experience and external performance.
As people grow older, they will go through more life stages and experiences, which will affect and shape a person's temperament to a certain extent. As an artist, Liu Pinyan's temperament has been continuously improved and enriched with the continuous accumulation and growth of her acting career.
However, temperament is not entirely determined by age. Some people may show a unique temperament at a young age, while others need to go through more life experiences before they can gradually exude a mature and stable temperament. So, while age is one factor that affects temperament, it's not the only one.
