Why did Kirin go to jail in Black Butterfly?

According to the plot of The Black Butterfly, Qi Lin, the black butterfly, was imprisoned for carrying smuggled goods. Although Qi Lin once said that she has a strong personality, she still has the innocence of a girl. Her biggest dream is to take a plane. At that time, she met a civil aviation pilot who promised to take her by plane. Qi Lin foolishly helped to buy electrical appliances. Finally, she learned that those electrical appliances were smuggled goods, and Qi Lin was arrested and imprisoned.
