The first song is also called a double song. In the traditional culture of China, the birthdays of the elderly are called birthdays. There are three kinds of longevity: the first is 60 to 80 years old, the middle is 80 to 100 years old, and the last is 100 to 120 years old. Shangshou, also known as Shuangshou, is the first of the three longevity. There is a saying in Lu Lun's "Offering a Provincial Duke at the Beginning of the Yuan Dynasty" in the Tang Dynasty: "Hanging clothes is the dawn, and longevity is opposite to Nanshan", so "the longevity of Nanshan" has become the highest symbol in China's blessing and birthday celebration culture. Since ancient times, there has been a folk saying that "I wish the East Sea a blessing and offer longevity to Nanshan", which is regarded as respect for longevity.
