2021 Year of the Ox Chinese New Year Chinese character greeting card creation. The epidemic situation in 2020 has brought a tremendous impact on our lives, making the network communication without tactile temperature and careful writing the best and safest way of blessing. The year 2021 begins with a speech blessing from an ox of the Chinese zodiac, which visualizes the sound wave combined with the onomatopoeic Chinese character 哞 "mou" emitted by the ox, forming a sound wave font with sound effect and showing the animation effect representing intensity of sound wave through 3D Printing Technology, implying that everyone's spring is coming with the arrival of the year of the ox.
