No answer. Because there is no direct connection between personal Douyin account and Ctrip link, you cannot directly link Ctrip to Douyin. However, you can mention relevant travel themes, attractions, etc. in the video to attract traffic, and then add relevant Ctrip discount codes or links below the video to achieve the effect of attracting traffic. Of course, if you are a partner of Ctrip Travel, you can contact Ctrip to obtain more cooperation methods and support.
