You can contribute to some music newspapers. For example, newspapers include Music Weekly and Music Life, and publications include songs. They all accept donations. You'd better buy it and read it first, and then write to them.

In addition, I have to pour a wave of cold water on you, and the medicine tastes bitter. If it doesn't sound good, it may help you. The lyrics seem simple, but you need to have high literary literacy and professional knowledge of music. You like to write lyrics, which is no problem, but it takes a lot of road and effort to get recognition from others. You study physical education. I don't believe you have received any formal art training. Of course, it does not mean that music majors can only write lyrics. And what you write, with only a little personal feeling or understanding, is difficult for others to recognize. It is also difficult to get the resonance of the songwriters.

So I have two suggestions. First of all, buy some professional books and learn and understand music and composition techniques. Second, find a job that suits your major. Don't think that music can bring you new development. There are many music professionals in China who dare not say anything about their development, let alone your present situation. Wouldn't it be better to write lyrics as your hobby and improve your artistic accomplishment if you have a job that suits your major?
