Rainie Yang stars in Taiwanese horror sequel 'Tag Along 2' TAIPEI, Taiwan (AP) — Taiwanese singer and actress Rainie Yang stars in "The Tag Along 2," a sequel to the 2015 hit that's loosely based on a ghostly urban legend in Taiwan about a little girl who appears in the footage of a family's hiking trip. In the sequel, Yang plays a social worker whose daughter goes missing in the mountains. [...] to avoid people getting sick during the filming of the sequel, and because it's very inconvenient to find a toilet (in wilderness), and also they didn't want the crew to get sick to delay filming, that's why at every set, there is a toilet just for our cast and crew, Yang said. Yang, who is friends with Hsu in real life, said that the challenges for both of them were to put aside their friendship and act like complete strangers when the cameras were rolling.
