Who invented paper and paper cutting? 
The art of paper-cutting (jiǎnzhǐ 剪纸) in China may date back to the second century C.E. since the paper was invented by Cai Lun in the Eastern Han Dynasty in China. As paper became more affordable, paper-cutting became one of the most important types of Chinese folk art. Later, this art form spread to other parts of the world, with different regions adopting their own cultural styles.

^[1]Usually, the artworks are made of red paper, as red is associated with festivities and happiness in Chinese culture, but other colors were also used. Normally paper-cutting artwork is used on festivals like Spring Festival, weddings, and childbirth. Papercuts always symbolize luck and happiness.
