Because Karry and Roy are the most popular children in the TF family, it is normal for them to be the first debutantes in the family. After all, they have accumulated such high popularity before. Jackson Yee was not originally a member of TF family, but a student of Time Star. He suddenly joined the TF family before the establishment of TF boys, that is, in the summer vacation of 20 13 (in fact, it seems that Qian Zong and Xiao Kai participated in the same program, which was filmed by the family in the background), and then he made his debut as TF boys. Jackson Yee is the only Beijing child among TFboys, and the other two are from Chongqing.
