The music single "Brother and Sister Love" commemorates the true love between brothers and sisters. The new song uses a beautiful lovesick melody and colloquial lyrics to describe the close and deep feelings between brothers and sisters, time and space. As time goes by, the annual rings pass through the memories of childhood. Today, we have all grown up, and each of us is busy with our own careers and lives. Thinking about us in the past, so many youthful years and so many happy times are now gone forever. . Looking at each other from far away, we miss each other without saying a word, and the days pass slowly in different spaces. Although every time we meet now is a short time, the emotions in the hearts of the brothers and sisters are always in their hearts. Give each other forever. Only with help, encouragement, and shared responsibility, Shi Jia expressed the deep friendship between brother and sister through singing.
