Only the art department of Shenzhen University can have a vocal music teacher to teach you. You can go to the art department of Shenzhen University to find a teacher to teach you when you are free. Farther away is the vocal music department of Guangzhou Xinghai Conservatory of Music, which is far away, but there is a special vocal music department. According to your situation, you are still at school, so you'd better go to Shenzhen to learn to sing. If you don't go to school after graduating from junior high school, you can choose to go to Guangzhou Xinghai Conservatory of Music to find a professional vocal music teacher. Then you can tell the teacher what you think and he will teach you how to do it.

Boys and girls are the same. I suggest you go to the art department of Shenzhen University to find a vocal music teacher first. He will guide you to become more professional. I am a piano teacher rather than a vocal music teacher, but I know that if you want to be a singer, you must let a professional vocal music teacher know about your situation and give you appropriate advice.
