Do China people regard Kang Shi as a student party that is not suitable for regular study?

I think it's appropriate. My child will have a mid-term exam soon. They use their eyes very frequently. They study in class every day, their eyes are often dry and they are often listless. To this end, I have done a variety of research, and chose the Korean eye cream, which has a good effect. Children will never say that their eyes are dry again, and they are more energetic than before.
