As a successful case of short videos on Chinese food “spreading overseas” on YouTube, “Goldthread” has effective cross-cultural communi-cation strategies, which provide a model for the cross-cultural communication of short videos dedi-cated to promoting Chinese food culture overseas. By constructing multi-modal cross-cultural sym-bols such as language symbols, audiovisual symbols, and emerging food culture symbols, as well as the wise use of image aesthetic technologies such as lens language, screen editing, colors, and ani-mation, the channel optimizes the viewing experience of the audience and improves its cross-cultural communication effect. From the perspective of video production, short videos on Chi-nese food should correctly use language symbols and accurately decode; make good use of audio-visual symbols; expand the symbols of gastronomic culture and update cultural memory; wisely use photography techniques to construct image aesthetics; adopt the perspective of civilians to promote flexible communication, and then improve the practice of cross-cultural communication.
