Lost Border is a band formed in the city of Jinan, known as the "Oasis of the South," towards the end of 2022. The band consists of lead vocalist Zhao Tianhao, guitarists Zhang Yulong and Zhang Yuanqi, bassist Liu Haoran, and drummer Chen Kangning.

Band name "Lost Border" originates from a roadside at dawn, when under the influence of alcohol, the thoughts are scattered and drowsy. At that moment, the first faint light pierced the sky, and everyone was on the edge of being half asleep and half awake, between the darkness and the light of day, and thus "Lost Border" was born.

Their song styles are just as their band name suggests, constantly wandering and jumping around at a certain intersection. Sometimes quiet, sometimes explosive; sometimes melancholic, sometimes humorous. Some long for the future, while others seem to want to perish immediately at this moment. Just like the yin and yang, the two styles alternate back and forth, giving the audience a feeling as if they are floating and sinking between dreams and reality. And they do not have a clear definition for their style. As they put it, they are just doing the music they like and the music they want to write.
