It seems you're asking about the video file featuring Kawakita Saika (presumably a typo for Kawana Saika ? — please check the actress name), with tags like “he bei cai hua” (possibly a transliteration or filename note) and “FHD-HEVC.”
The video is approximately 180 minutes long, divided into 7 distinct segments or "corners". SSIS-334 Kawakita Saika he bei cai hua -FHD--HEVC-
