In 2016, the group released This Is China, showing their love for the country, rapping about issues such as air pollution, food safety and corruption.

Li, who graduated as an English major from Sichuan Normal University, wrote the lyrics of This Is China in English since the group wanted to directly communicate with foreign audiences in the four-minute song. The video of the song has been viewed more than 10 million times.

Last October, the group collaborated with veteran Chinese singer Li Guyi, adding a rap element to the popular Chinese song, Me and My Motherland, celebrating the 70th anniversary of the founding of the People's Republic of China.

"When we first started out as a hip-hop group, we didn't want to be like many other rappers, who sing with explicit lyrics. Hip-hop culture is often associated with negative things like drugs and violence, however, we want to make a difference," says Wang.

"Young Chinese rappers can write in a unique style, telling stories about their daily lives, which can be so cool."
