Justin Bieber, of course. How can Jason compare with B Bao? Jason only develops in China and its surrounding areas, and his popularity is limited. But Justin Bieber is developing all over the world. Belieber is found all over the world, and he is also the prince of European and American pop music. He is good at music creation, drumming, dancing, playing guitar, piano and so on. No one can match him. He made such great achievements at such a young age, and also produced the "Bieber effect". He is willing to take part in charity activities and has won numerous awards. . .

Both software and hardware are Justin Bieber. It's good.
