Jackie Chan, who has a good positive image, is indeed the perfect spokesperson pursued by many brands, but the decline of some brands caused by social progress is beyond Jackie Chan's control. It is really helpless to be given such a title. In fact, many of Jackie Chan's products were popular brands at that time, but the biggest brands couldn't keep up with the internet age and had to be eliminated. Those once familiar brands failed to keep pace with the times and closed down one after another, so Jackie Chan was named as "advertising killer".
