Having a bi cultural identity is one of the special aspects about being bilingual or multilingual. The term bi cultural identity is the condition of being on self-regarding the combination of 2 cultures.
We also have cultural effect, which is the shared behaviours and customs we learn from the institutions around us. Examples include how a person’s personality is influenced by the people who are around them. And how some societies it would be more acceptable to dress or actin a certain way. Culture effects the personality of an individual may react in a way that is reflective of the knowledge someone acquires from one or more cultures.
Problems may begin when ideals in one culture are not connected to another culture which may cause generalizations about personality. I think having a bi cultural identity is good because you have/understand more than one culture.
