I often vomit every day after schizophrenia, but practicing calligraphy will be much better. Why?

Spitting every day may not be directly related to schizophrenia, but may be caused by other diseases such as throat disease. The reason why people can alleviate the symptoms of spitting related to calligraphy is that people are highly focused when practicing calligraphy, and they don't deliberately care whether their throats are uncomfortable when they are engaged, so they don't spit often.
