I hope that the Chinese native speakers can realize the interest in the original nijisanji video, however, the video didn't allow the viewer to add the cc subtitles. Thus, I use this method to promote it. If this conduct offends the copyright, I would be very willing to remove this video. Sorry for using English to reply to your comment, cuz I want to use the most proper words to convey my thoughts. It's not my meant to make you feel offensive. Edit: BTW this channel doesn't profit from those videos. I also put the original video source and liver link in the description column. Thanks for your comment to ask for the copyright. Edit2: As for your question, the official nijisanji 's attitude seems like if the channel doesn't gain the profit, it will be acceptable. Hope that I can have your response soon.
