What do you think of Andrew's suggestion that Chiu Man-Cheuk should not rap in Northeast dialect?

Every brother has his own characteristics, and it is inevitable that there will be quarrels. After all, every brother has his own opinions and ideas. Coming to this stage, he also hopes to dedicate himself to the best stage in his mind. I think it's right to sing and rap without using Northeast dialect. First of all, rap is not easy. In all kinds of programs, rap jokes are common, so it may be difficult for so many people to sing in Mandarin, let alone in Northeast dialect. For Chiu Man-Cheuk, who has never learned rap, it is not only very difficult, but even a great difficulty to rap in Northeast dialect. Just to overcome Mandarin, rap should be sung well and rhythmically. This is already a big problem. Singing in Northeast dialect is simply making it more difficult for yourself, which is totally unnecessary. Moreover, rap in Northeast dialect is likely to become very funny. Playing Andrew doesn't want his stage to become a very funny picture, so he can make a short video to be funny. Andrew knows a lot about the Internet because he often goes online. Of course, he knows what the audience will laugh after seeing the Northeast dialect rap, so he knows this situation better than Chiu Man-Cheuk, hoping to sincerely persuade him not to sing in Northeast dialect. The tone of Dongbei dialect itself is a bit funny. After serious rap, it really makes people feel a bit like playing tricks. The presentation effect on the whole stage is not good. So I think Andrew, as a junior, can take the initiative to persuade, and he can start from the effect of the whole stage, which I think is very good. He is afraid to speak because of his status. For the sake of the whole stage, he will make such a suggestion, and everyone should treat it rationally.
