On April 24, Scienjoy visited San Shizhai in Peking. San Shizhai's kite heritage has a history of over a hundred years and is an important representative school of kites in Peking. What catches the eye at San Shizhai is the various kites of all sizes hanging on the walls. There are sharp-eyed, majestic eagles; mighty and domineering phoenixes; and various swallows of different shapes, all kinds of kites are visible. The owner of San Shizhai, Mr. Liu Bin, as a representative inheritor of the national intangible cultural heritage projects "Cao's Kite" and "Liu's Kite", learned the kite making skills from his grandfather, Liu Hui Ren, and later visited famous teachers, obtained the authentic skills of Cao's Kite, and combined Cao's Kite's temple, palace, and folk styles to form his own kite making style.
