The Northeastern dialect of Bullet Case was learned from YY.

Those who control the entire YY rap scene are Northeastern brothers. Beibei once taught rap on YY. The YY platform gave birth to the predecessor of Shoumai, which is the five-item rap dominated by Northeast culture, and derived a set of "tutorials" to teach others how to record and rhyme. And because in YY at that time, rap was one of the five categories. In their early years, both Shell and Beibei were involved in the YY platform, and Beibei spent a lot of time on YY. Beibei met PG One on YY.

Liu Jiayu (November 4, 1992-), also known as "Bullet Shell", graduated from Xi'an Conservatory of Music and is a Chinese hip-hop male singer. He is the founder of the HIPHOP team "Red Flower Club", and his solo album "Illusion Humanity" has received numerous praises.

Early life experience

In 1992, Shell was born in Guangdong Province. His father worked in the automobile trade, so his living conditions were relatively comfortable since he was a child. When he was three years old, Shanghui's mother wanted him to become a performer and spent money to buy a piano at home, so Shanghui began learning piano at the age of three. When he was in high school, he came to Xi'an and studied in the keyboard department of the High School Affiliated to Xi'an Conservatory of Music. Starting from his sophomore year in high school, Shell started listening to hip hop music and started trying to write lyrics on his own.

Later, I met Ding Fei, a fellow Hip Hop enthusiast, in a shopping mall. The two often got together to battle and rap impromptu. After that, he began to practice impromptu rapping on the YY Voice rap channel. In college, Shell studied in the Electronic Music Engineering Department of Xi'an Conservatory of Music. According to his family's expectations, he should have become a film scorer. However, after being rebellious since childhood, she went to a liberal university where she was free and relaxed. She was always getting into trouble and fighting, and rarely went to class.
