According to Securities Times, the auto market in 2024 is still engulfed in fierce competition. Nowadays, the automotive market has evolved from technology and price competition to marketing competition. Recently, top executives of many vehicle manufacturers have been actively promoting marketing through live broadcasts, short videos and other forms of interactive media. It has almost become a consensus in the industry to promote sales efforts by all staff. However, in the process of intense marketing, some malicious tactics such as criticizing competitors or slandering the competition have begun to emerge in the industry. Recently, the dealers of Great Wall Motor's Wei brand were punished by the Market Supervision Administration in Xiqing District, Tianjin, for comparing their competitors aggressively in their promotion tactics. Although the distributors' behavior does not necessarily represent the stance of the automaker, the use of abnormal marketing tactics in terminal sales can still damage the commercial and product reputation of the competitors, and even cause more negative and widespread impact.
