YH has this nickname 网红, which means he's very popular on the internet.
We know how he worked so hard to use Chinese to interact with the fans. The reporters are particularly impressed that he's able use internet slang like "dang" and wondered if he knew the origin of that. YH knows! It came from Jackie Chan's shampoo CF in China. When asked how come he knows so much, he said sometimes he asks the staff and most of the time, fans mention him on weibo for all these interesting info. So he really has fun interacting with fans on weibo.

Thanks klaritia and heich for the hardwork as always :)
Here are some added stuff:
-(first answer): On~~~New~~Years~~ I stayed home. I had no schedule that day, but I had OFD concert practice the day after. So I couldn’t rest much, but everyone who prepared for the OFD concert couldn’t rest on New Years day. I think the result of such hard work is reflected in the result that we could probably show tomorrow.
-After the part klaritia translated:
He really feels that the Chinese fans are sending him so much passionate support, especially through weibo and SNS. That makes him happy as he promotes with many activities.
