In ancient times, the word "Yu" was a honorific term for what the emperor did and what he used, and the sofa had a strong sense of lines, presenting a noble and upright spirit of the ancient emperor. Lines crisscross each other, making people feel like they are in a semi open cage. Although the space is small, they don't feel depressed. The furniture is decorated with copper strips and horned flowers, and all kinds of elements are used properly, which makes the furniture have both classical and modern charm.
