The history of Chinese fans goes back to the Shang Dynasty (朝代) ( about 1600 B. C~1046 B. C). One of the earliest fans was known as Shanhan. It was a bit like today's umbrella. It tried to keep people away from the strong sunshine and rainfall. Later, Shanhan developed into a long- handled fan called Zhangshan(障扇).
In fact, the fan was not used to help people cool down until the Zhou Dynasty. At that time, fans were usually made of birds' feathers and mainly used by the emperors. Later, bamboo fans and cattail- leaf fans(蒲扇) were invented during the Han Dynasty. Both were most popular among the common people during the Song Dynasty.
Years later, the folding fan was introduced. It soon became popular. However, the best thing of a folding fan was the pictures on it. If a famous person painted the fan, it could cost a lot of money. For example, a folding fan painted by Zhang Daqian was sold for$252,000. Qi Baishi and Xu Beiho ng were also well known.
Throughout history, Chinese fans have stood the test of time. Today, there are more than 500 kinds of fans in China, attracting a great number of fan lovers both at home and abroad. However, it's difficult to carry on our traditional skills of making fans among young people now for many reasons. Luckily, Tag Design madea meaningful try.
