Physics includes theoretical physics, applied physics, nuclear physics, condensed matter physics, astrophysics (astronomy-related), physical electronics (electronics-related), optics and optical information processing (communication-related), microelectronics technology (electronics-semiconductor-related), mechanics (a first-class discipline parallel to physics, which is divided into many small disciplines below), physical chemistry (chemistry-related), acoustics and heat (engineering-related).

Which one has a future depends on how you do it. Theoretically, it is suitable for further study, scientific research and education abroad; Engineering application is suitable for related work.
