Bottom line: Happy New Year to Golden Mouse.
Main advantages: Couplets originated from the symmetry of characters and sounds in China, which appeared before the Zhou Dynasty. With the development of papermaking and calligraphy, couplets have become an independent style.
Couplets are short in form and concise in words, which is not only a vivid artistic expression, but also an excellent cultural heritage. Couplets are developed on the basis of ancient "Fu Tao" and "antithesis". The earliest Spring Festival couplets in China appeared more than 1000 years ago.
