Liu is a virtual character. Liu is not a real person, but a virtual character built by post-film technology. Different from other virtual idols, Liu can be said to be the first to spread through short videos and content creation. Liu is not made by software alone. Simply put, Liu belongs to the hyperuniverse. Metauniverse is essentially a virtual and digital process of the real world, which needs a lot of transformation in content production, economic system, user experience, physical world content and so on. This virtual character (anime character) was made by Fei Feiyu and Hui Hui Zhou NG, and the company behind it was Shenzhen Chuangyi Technology. From the perspective of video production, the lines of the characters are clear. There were flowers in the late Tang Dynasty, and there were gold, arch eyebrows, rouge and crimson lips on the makeup, which had the feeling of "light makeup and peach face, full face of flowers" and had the characteristics of exquisiteness, compactness and elegance.
