Despite the new technological effect and newer method of online communication it has brought, this investigation is planned to discover the effect of TikTok's information on the teenagers in Shenzhen China, and the further correlation between the viewing the short videos in TikTok and its impact on teenager's stress and anxiety level. The investigation is launched by delivering electronic questionnaire to Shenzhen's high school students and teenagers aged from 13 to 20. From the results, it is discovered that the teenagers in Shenzhen have been impacted by the information in TikTok in a small extent due to their higher level of education. However, a positive correlation of teenage stress level and the intensity of viewing TikTok has been investigated. It has been discovered that as juveniles and high school students are familiar with the viewing short video, they will be less efficient at work after viewing TikTok. This results to an increasing level of the general stress level and usually triggers the increasing level of anxiety as the teenagers find themselves fail to achieve their expected targets in time.
