Of course, the best age is when you go to college. After graduating from high school, you have the opportunity to choose a university major. You can choose this aspect. This is your freedom. Art students can choose, and most of them are art students. Some schools allow general culture candidates, while others do not. This may be related to local policies and the school's enrollment strategy. When they go to college, they always just entered the university. They should be seventeen or eighteen.
This major has certain requirements for your personal conditions, such as pronunciation, such as your Mandarin. If your Mandarin is not up to standard, it will be very troublesome. If you want to take the Chinese teacher qualification certificate in senior high school, you must have at least Grade A in Putonghua, and if you want to be a broadcast host, you must have at least Grade B in Putonghua examination. Most broadcast hosts are Grade A, which is the most standard.
There are prospects, but you have to study well enough and work hard enough. For example, you should spend some time practicing your voice every morning. When you speak, you should open your voice to ensure that your voice is full of gas, your voice is stable, and there is no sudden tone fluctuation. This requires long-term practice. Just like a job that you have repeated countless times, practice makes perfect, and there is no particularly good way to make you very good in a short time.
