the meaning of "left and right" is taken from the essence of China's ancient philosophical thought "the doctrine of the mean"-"deficiency is the truth, middle is the truth, and fullness is the repetition", which is impartial. The "Left and Right Sofa" is named after China's ancient philosophy, and is represented by modern geometric concepts. The trademark of the period has profound connotations: three dots, namely, upper, middle and lower dots, respectively representing the concepts of the universe of heaven, earth and human beings, and two brackets, one left and one right, implying that being in the universe should be impartial and mean, and it has the boldness and mind of integrating ancient and modern Chinese and foreign.
