I wonder what the landlord asked the OPPO player? As far as I know, the players that come with OPPO are all Oplayer players. The music movement is a music movement by Orson, England. Non-intelligent machines like OPPO usually bring their own players to listen to songs. I guess the landlord saw the point where the chick played the piano behind the OPPO screen in the advertisement. In fact, it is not the music player of OPPO, but the video player of T9. Just look at the play button. I wonder if the landlord asked this question.
