The birthday girl over 80 years old should be hung opposite the main entrance of the living room. Generally hung in nave as a general living room. There are separate Chinese characters such as "shou" and "fu" to hang. Couplets are hung on both sides. The first part is "Happiness is like flowing water in the East China Sea" and the second part is "Longevity is better than Nanshan". These three constitute the overall effect and convention of an art.

Longevity culture is an important part of China's traditional knowledge, which is extremely incisive in classic documents such as The Book of Songs and Laozi. After thousands of years of development, the longevity culture is becoming more and more perfect. People of all ethnic groups in China have developed colorful birthday customs. For example, 60 is called the first birthday, 80 is called the middle birthday, and 100 is called the high birthday. Another example is Happy Birthday at 77, Mi Birthday at 88 and Bai Shou at 99. Among the three stars of Fu Lushou, there is a longevity star. In idioms, longevity is better than Nanshan, and in everyday language, there is health and longevity.
