A group led by Lin Cunzhen, an associate professor at the China Central Academy of Fine Arts, designed the Beijing 2022 pictograms. It took the team about six months to complete the project. Input from experts or International Sports Federations contributed to the design refinement. The style of the pictograms recalls the graphics culture of the country and interprets, in a modern form, the traditional Chinese art of seal engraving of the Qin and Han dynasties where a knife was used to create the design. The contrast between the red and the white adds a festive touch and highlights the dynamism of the various sport disciplines. In line with the style of the Beijing 2022 emblem, these pictograms also pay tribute to those of the Olympic Summer Games in Beijing in 2008.
